    Abstract: The present disclosure provides a series of new and improved porous polyamide aerogels derived from multifunctional aromatics that combine the high mechanical strength of aramids with the pore structure of aerogels. The polyamide aerogels have a hyperbranched structure, relatively low density, high porosity and are derived from functionalized monomers having more aromatic groups than functional groups. The present disclosure also provides a new method for producing the porous polyamide aerogels by polymerizing an aromatic multifunctional carboxylic acid with an isocyanate at moderate reaction condition followed by drying with liquid CO2.

  • Publication number: 20130210621
    Abstract: A breathable film formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure is provided. To achieve such a structure, a thermoplastic composition that contains a renewable polyester and polymeric toughening additive is extruded onto a surface to form a precursor film in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor film is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). Without intending to be limited by theory, the present inventors believe that the deformation force and elongational strain of the drawing process causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This creates a network of voids located adjacent to the discrete domains.

  • Publication number: 20120061867
    Abstract: A process for the manufacture of a plastic part, the process comprising providing a polymer, heating the polymer, introducing a gas or supercritical fluid into the polymer, mixing the polymer and the gas to produce a first melt, extruding the first melt, pelletizing the extruded first melt to form pellets, transforming the pellets into a second melt, and molding the second melt to form the plastic part. In pelletizing the first melt, individual cells of gas are included in the resulting pellets. Before the cells can nucleate, the polymer is solidified to keep the gas contained therein. After the polymer is pelletized, the pellets are considered to be unfoamed. In molding the second melt to form the plastic part, nucleation of the cells is initiated through favorable process conditions and/or additional cell nucleating agents, thereby resulting in the second melt being foamed.

  • Patent number: 8119701
    Abstract: Disclosed is a method for making polystyrene foam which utilizes one or more atmospheric gases, particularly combinations of HFCs and CO2, as the blowing system in combination with a polymer processing aid (PPA), typically an ester that is relatively non-volatile at the extrusion temperature range. The blowing system and the PPA may both be introduced into the molten thermoplastic polystyrene resin or the PPA may be incorporated in the solid source polystyrene resins. The resulting foams will typically exhibit improved dimensional stability at ambient temperatures.

  • Publication number: 20120010307
    Abstract: The invention provides a composition and process for producing expandable beads from a compostable or biobased thermoplastic polymer. A key aspect of this invention is the ability to incorporate sufficient amounts of hydrocarbon blowing agent into the matrix of the compostable or biobased polymer. The following process may be used. First, the raw materials of compostable or biobased polymers, hydrophobic additive, and other additives are mixed by melt processing techniques. Next, a hydrocarbon blowing agent is added to the admixture, either by addition into the melt or by impregnation into the solid, to produce an expandable bead. Small, lightweight, foamed beads are produced by heating the expandable bead. Then, the expanded beads are subsequently used in conventional operations for molding into foamed articles.

In exemplary embodiments, the blowing agent includes at least one hydrofluorocarbon blowing agent. The maleic anhydride-styrene copolymer grafted with polyethylene oxide provides a water vapor permeability of 1.1 perm inch or greater in the extruded foam product without detrimentally affecting physical or thermal properties of the product. Additionally, the copolymer of maleic anhydride-styrene grafted with polyethylene oxide has a positive affect on the processability of the blowing agent(s) in the composition by both widening the process window and enhancing the solubility of the blowing agent in the polymer melt. Thus, the polystyrene/polyethylene oxide copolymer present in the inventive composition acts as a cell enlarger, a plasticizer, and a processing aid.
