Publication number: 20160177048Abstract: A polymeric material having anisotropic properties, such as mechanical properties (e.g., modulus of elasticity), thermal properties, barrier properties (e.g., breathability), and so forth, is provided. The anisotropic properties can be achieved for a single, monolithic polymeric material through selective control over the manner in which the material is formed. For example, one or more zones of the polymeric material can be strained to create a unique network of pores within the strained zone(s). However, zones of the polymeric material that are not subjected to the same degree of deformational strain will not have the same pore volume, and in some cases, may even lack a porous network altogether.Type: ApplicationFiled: June 6, 2014Publication date: June 23, 2016Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Vasily A. Topolkaraev, Ryan J. McEneany, Neil T. Scholl, Mark M. Mleziva

Publication number: 20160168349Abstract: Microparticles that have a multimodal pore size distribution are provided, Notably, the pore structure of the present invention can be formed without the need for complex techniques and solvent chemistries traditionally employed to form porous microparticles. Instead, the microparticles contain a polymeric material that is formed from a thermoplastic composition, which is simply strained to a certain degree to achieve the desired porous network structure.Type: ApplicationFiled: July 9, 2014Publication date: June 16, 2016Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Vasily A.

Publication number: 20160121523Abstract: A technique for initiating the formation of pores in a polymeric material that contains a thermoplastic composition is provided. The thermoplastic composition contains microinclusion and nanoinclusion additives dispersed within a continuous phase that includes a matrix polymer. To initiate pore formation, the polymeric material is mechanically drawn (e.g., bending, stretching, twisting, etc.) to impart energy to the interface of the continuous phase and inclusion additives, which enables the inclusion additives to separate from the interface to create the porous network. The material is also drawn in a solid state in the sense that it is kept at a temperature below the melting temperature of the matrix polymer.Type: ApplicationFiled: June 6, 2014Publication date: May 5, 2016Inventors: Vasily A. Topolkaraev, Ryan J, McEneany, Neil T. Scholl, Antonio J. Carrillo, Mark M. Mleziva

Patent number: 9271487Abstract: A method for forming an antimicrobial composition that includes mixing an antimicrobially active botanical oil (e.g., thymol, carvacrol, etc.) and protein within a melt blending device (e.g., extruder) is provided. Despite the problems normally associated with melt processing proteins, the present inventors have discovered that the processing conditions and components may be selectively controlled to allow for the formation of a stable, melt-processed composition that is able to exhibit good mechanical properties. For example, the extrusion temperature(s) and shear rate employed during melt blending are relatively low to help limit polypeptide dissociation, thereby minimizing the impact of aggregation and embrittlement.Type: GrantFiled: May 22, 2013Date of Patent: March 1, 2016Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Vasily A. Topolkaraev, Neil T. Scholl, Jaehong Lee, Dianna L. Ambrose, YoungSook Kim

Patent number: 9205152Abstract: A melt-processed protein composition formed from a protein, plasticizer, and an electrophilic reagent is provided. The electrophilic reagent, for instance, may be selected to undergo a nucleophilic addition reaction with free sulfhydryl and/or thiyl radicals to help minimize the formation of disulfide crosslinking bonds that could otherwise lead to protein aggregation during melt processing. To enhance the degree to which the electrophilic reagent can limit crosslinking, a plasticizer is also employed that helps to mediate the adsorption of the electrophilic reagent into the internal structure of the protein, where it can be more stably retained. Furthermore, the temperature and shear rate employed during melt blending may also be selected to be relatively low to help limit polypeptide dissociation, thereby minimizing the impact of aggregation and embrittlement.Type: GrantFiled: April 16, 2013Date of Patent: December 8, 2015Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Vasily A.

Patent number: 9149045Abstract: An oil-in-water emulsion that is environmentally friendly and also exhibits antimicrobial activity is provided. More specifically, the oil phase of the emulsion includes a botanical oil derived from a plant (e.g., thymol, carvacrol, etc.). Because the botanical oil tends to leach out of the emulsion during storage and before it is used in the desired application, a water-dispersible polymer is also employed in the aqueous phase of the emulsion to enhance long term stability of the oil and, in turn, antimicrobial efficacy. Without intending to be limited by theory, it is believed that the water-dispersible polymer can effectively encapsulate the botanical oil within the emulsion and inhibit its premature release. Once the emulsion is formed, water can then be removed so that it becomes a substantially anhydrous concentrate. In this manner, the water-dispersible polymer will not generally disperse before use and prematurely release the botanical oil.Type: GrantFiled: December 7, 2010Date of Patent: October 6, 2015Assignee: Kimberly-Clark Worldwide, Inc.Inventors: JaeHong Lee, Vasily A.

Publication number: 20150225565Abstract: A thermoplastic composition that contains a rigid renewable polyester and has a voided structure and low density is provided. To achieve such a structure, the renewable polyester is blended with a polymeric toughening additive to form a precursor material in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor material is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). This creates a network of voids located adjacent to the discrete domains, which as a result of their proximal location, can form a bridge between the boundaries of the voids and act as internal structural “hinges” that help stabilize the network and increase its ability to dissipate energy. The present inventors have also discovered that the voids can be distributed in a substantially homogeneous fashion throughout the composition.Type: ApplicationFiled: April 24, 2015Publication date: August 13, 2015Inventors: Neil T. Scholl, Ryan J. McEneany, Thomas A. Eby, Vasily A. Topolkaraev

Publication number: 20150159012Abstract: A film that is formed from a thermoplastic composition is provided. The thermoplastic composition contains a rigid renewable polyester and a polymeric toughening additive. The toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. An increase in deformation force and elongational strain causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This can result in the formation of a plurality of voids adjacent to the discrete domains that can help to dissipate energy under load and increase tensile elongation. To even further increase the ability of the film to dissipate energy in this manner, the present inventors have discovered that an interphase modifier may be employed that reduces the degree of friction between the toughening additive and renewable polyester and thus reduces the stiffness (tensile modulus) of the film.Type: ApplicationFiled: February 10, 2015Publication date: June 11, 2015Inventors: Vasily A.
