New Developmental Copolyester
Katherine Hofmann, Eastman Chemical Company
Eastman Chemical Company has developed a new co-polyester that combines the best of Spectar™ and Tritan™. The material has high heat resistance, strength, and stiffness as well as a number of other desirable characteristics. These include a low coefficient of friction, excellent ultrasonic welding, and great chemical resistance. The material is also excellent for injection molding, reheat stretch blow molding, injection stretch blow molding, extrusion blow molding, and extrusion. In addition, bio-content or recycled content can easily be incorporated. The characteristics of this new polymer enable molding and design freedom in a number of applications with the clean chemistry of copolyesters.

Nylon6,6 rich Co- and Terpolymers: How Tuning Thermal Behavior Enhances Functionality and Enables New Application Spaces
Jacob Ray, Ascend Performance Materials
Polyamide6,6 (PA66) is a semi-crystalline thermoplastic that has many useful functions such as high temperature resistance (melting point = 260 C), strength, toughness, barrier, and chemical resistance. Further, its fast rate of crystallization is often beneficial for fast cycle times of injection molded parts, yet it can be a limitation in many cases. For one, highly filled systems that may include glass fiber or other additives usually have fair to poor surface aesthetics. In the case of film extrusion, PA66 has many limitations such as but not limited to blown film processability, aesthetics (poor haze and gloss), and post orienting and thermo-forming. Through incorporation of additional monomers that do not co-crystallize with PA66 to produce PA66 rich co or terpolyamides, one can reduce crystallization rate up to 100 fold while maintaining semi-crystallinity and a high melting point (> 215 C). Through reducing the rate of crystallization, enhanced properties can be achieved that augments the high melting point enabled by a PA66-rich backbone; these enhanced properties include (1) improved aesthetics (i.e., higher gloss and clarity), (2) larger processing windows for extrusion or blow molding, and (3) toughness (i.e., puncture resistance). These functional benefits enable PA66-rich copolymers to bring value into a variety of film application spaces from monolayer cooking bags to multilayer films for industrial and food packaging. In a converse strategy, this disclosure will touch briefly on increasing melting and crystallization temperature, driven by incorporation of co-crystallizing monomers; this strategy empowers other functional improvements such as improved wear resistance and thermal aging performance that can bring value in a number of industrial and automotive applications.

Tailor-Made UHMWPE by High Shear Polymer Modification
Binay Patel, Zzyzx Polymers, LLC
The physical properties for commodity polyolefins have steadily improved over the course of the last 30 years. Some of these developments have been accomplished by optimizing structure-process-property relationships. For example, it is known that the longest of polymer chains can act as tie molecules between crystalline lamella, thereby increasing toughness but decreasing processability. It is also known that a balance of properties is often achieved by tuning a resin’s molecular weight distribution (MWD) for a given application. There have also been improvements in single site catalysts that can be used either within the same reactor or within reactor cascades to better control the resulting MWD. Unfortunately, these improvements have not translated to new ultra high molecular weight polyethylene (UHMWPE) materials. Improvements developed for commodity polyolefins do not translate to polymerization control at very high molecular weights. Zzyzx Polymers, LLC has developed a high shear polymer modification (HSPM) process for producing tailor-made UHMWPE thereby expanding the commercial utility of UHMWPE. This technical marketing presentation will cover an overview of HSPM technology and highlight various examples for tailoring UHMWPE for improved material performance, processability and for developing commercially viable UHMWPE-based blends.

Low Emission Compounds – Automotive Specifications & Applications
Tanmay Pathak, A. Schulman
Polymer composites used in automotive interior applications are nowadays subjected to much higher emission standards with increasing knowledge of adverse effects of emissions on human health. As such, Low Emission products are highly sought after in the automotive industry for such applications which include measuring Odor and Fog, Volatile Organic Compounds (VOC’s) and Semi-Volatile Organic Compounds (SVOC’s). A. Schulman, Inc. has globally developed glass and mineral filled composites that meet the regulatory requirements for VOC’s and SVOC’s in GMW, VW and Daimler Benz specs through a careful selection of base polymers, additives and compounding technology which will be highlighted in this work. The development of this work needed thorough understanding of the Emission requirements outlined by various OEM’s across several polymers including polyolefins, polyamides, styrenics, polyketones and acetals. This presentation highlights the automotive emission specifications needed to be met across these polymers and the commercial grades that fulfill those requirements.
Paul Tatarka, TOPAS Advanced Polymers, Inc.
Cyclic olefin copolymers (COC) provide film manufacturers and converters with an opportunity to create thin, stiff, and high barrier protective packaging products. Protective packaging is an excellent illustrative application to showcase COC as effective and efficient polyethylene modifier. Key COC performance benefits include low nitrogen and water permeability, higher stiffness, lower tear resistance and broad heat sealing window.

Biodegradable PHA for Use in Fashion Textiles
Anne Schauer-Gimenez, Mango Materials
Mango Materials has developed an innovative platform technology to turn waste gas streams into ecofriendly, biodegradable materials at competitive economics. Utilizing a biological process, microorganisms convert the carbon from methane into polyhydroxyalkanoate (PHA), which can be formulated to produce various products. The recent application development of biodegradable bio-polyester production will be highlighted. By substituting persistent polyester with this biodegradable bio-polyester made of PHA, brands can finally produce truly sustainable garments. Until now PHA has never been developed into commercial textile fibers, making this discovery an opportunity to accelerate the market growth of PHA.
