Patent number: 9732021Abstract: This specification discloses an operational continuous process to convert lignin as found in ligno-cellulosic biomass before or after converting at least some of the carbohydrates. The continuous process has been demonstrated to create a slurry comprised of lignin, raise the slurry comprised of lignin to ultra-high pressure, deoxygenate the lignin in a lignin conversion reactor over a catalyst which is not a fixed bed without producing char. The conversion products of the carbohydrates or lignin can be further processed into polyester intermediates for use in polyester preforms and bottles.Type: GrantFiled: February 24, 2013Date of Patent: August 15, 2017Assignee: Biochemtex S.p.A.Inventors: Steven Ryba, Aaron Murray, Guliz Arf Elliott, Dan Gastaldo, Edwin A Sisson, Ehsan Moharreri, Krishna Sharma

Patent number: 8535772Abstract: A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked. Method for producing the article and for masking the haze are also provided.Type: GrantFiled: October 10, 2012Date of Patent: September 17, 2013Assignee: M&G USA CorporationInventors: Edwin A.

Patent number: 8231937Abstract: Compartmentalized chips of at least two chemically similar crystallizable thermoplastic polymers each having a different intrinsic viscosity placed in separate zones are disclosed. These compartmentalized chips exhibit thermal characteristics that are different from the traditional technique of homogeneously combining the two materials into the chip. These compartmentalized chips in their amorphous, crystalline and solid phase polymerized forms exhibit a longer crystallization half time than the homogeneous mixture, thus permitting faster injection cycle times when compared to an equivalent homogenous mixture.Type: GrantFiled: July 8, 2011Date of Patent: July 31, 2012Assignee: M&G USA CorporationInventors: Delane Nagel Richardson, Edwin A.

Patent number: 7816008Abstract: This invention discloses a process and a necessary article to simultaneously thermally treat at least two thermoplastics. The process utilizes the necessary compartmentalized or zoned pellet construction wherein the major amount of each thermoplastic component is located within individual compartments or zones of the pellet such that the components of the reaction during thermal processing and/or reactions with compounds in the atmosphere such as oxygen are less than the reaction if the thermoplastics were homogeneously dispersed in the pellet. This invention allows the components of the multi-component pellets to be thermally treated together without significant degradation and/or stored in air or in the presence of oxygen without significant degradation.Type: GrantFiled: May 15, 2009Date of Patent: October 19, 2010Assignee: M & G USA CorporationInventors: Gianluca Ferrari, Edwin A.
