Abstract: Polyamide compositions for use in forming wire or cable jacket compositions. The polyamide compositions include a component of polyamide 6/66 copolymer formed from substantially randomly distributed caprolactam monomers and hexamethylenediamine monomers. The polyamide 6/66 copolymer component may form the entirety of the polyamide composition or alternatively, the polyamide composition may include an amount of polyamide 6 homopolymer blended with the polyamide 6/66 copolymer component. The composition also includes one or more additives, such as at least one UV mitigation component, and the polyamide composition further has at least one of a measured transmittance of at least 70% and a measured haze of less than 60%, as determined by ASTM D1003.

The composition also includes one or more additives, such as at least one UV mitigation component which, due to the reduced crystallinity of the polyamide 6/66 copolymer component, is incorporated into the polyamide composition with desirable transmission and haze characteristics as well as providing for retention of physical properties such as tensile strength at break and elongation at break.

Abstract: Polyamide base resins with improved crystallization dynamics for the production of reinforced polyamide compositions having improved surface, shrink, warpage and mechanical properties such as toughness. The polyamide base resins are copolymers of polyamide 6 and polyamide 66, formed of ratios that are tailored to reduce the crystallization rate and final crystallization extent when used in melt processing to produce glass filled articles. The copolymers demonstrate improved polyamide morphology dynamics that in turn impart improved final properties in reinforced molded articles, such as improved surface finish, improved toughness/impact resistance, reduced warpage, and more symmetrical shrinkage properties.

Abstract: Methods for mixing nylon compounds and compositions useful in mixing nylon compounds are provided. The methods and compositions disclosed are useful in producing nylon for wire and cable jacketing. The disclosed methods provide nylon having a reduced heat history compared to traditional methods.

Abstract: A polyamide composition is formed by combining a phosphorous containing catalyst with monomer starting materials under conditions suitable to cause polymerization of the monomer starting material into a low molecular weight polyamide material. The polyamide material, which may include remaining or residual catalyst, is then further polymerized via solid state polycondensation at a temperature suitable to form a high molecular weight polyamide material. The presence of the catalyst results in increased solid state polymerization rate and a final polyamide material composition with increased viscosity and a higher molecular weight.

The polyamide also includes un-terminated endgroups, where a difference between a concentration of carboxylic acid endgroups and a concentration of amine endgroups is about 5 meq/kg or less.

Abstract: High gas barrier, delamination-resistant polyamide compositions suitable for extended shelf-life packaging applications are provided. Also provided are polyamide compositions exhibiting high oxygen scavenging capability. The polyamide compositions comprise mXDA-IPA containing copolymers which provide excellent properties to the complete polyamide compositions. Also provided are direct blends of the polyamide compositions with other polymers. The polyamide products are particularly suited for producing barrier packaging articles such as monolayer or multi-layer films, sheets, thermoformed containers and molded bottles. Such articles are useful in a variety of oxygen-sensitive food, beverage, pharmaceutical, and health care product packaging applications.

Abstract: The invention relates to epoxy-terminated polymers and copolymers derived from hydrosilyl-terminated hydrogenated polydienes and polyvinyl aromatics, and a process for preparing these polymers and copolymers. The epoxy-terminated polymers and copolymers are reactive with a variety of polymer functionalities such as carboxyl, hydroxyl, and amino groups to produce copolymers useful as molded articles and as compatibilizers for compositions containing polyesters and polyolefins.
