Amorphous polyamide terpolymers with a high level of transparency, transition glass temperature, flexibility, and chemical resistance. In one embodiment, the polyamide terpolymers are polymerized from caprolactam, at least one diamine, and at least one diacid.

Polyamide terpolymers for manufacture of transparent articles

Bibenzoate copolyesters are based on (4,4'-biphenyl dicarboxylic acid-co-3,4&#x2032;-biphenyl dicarboxylic acid) as the diacid component, and on an alicyclic diol compound such as 1,4-cyclohexanedimethanol as a portion of the diol component. Copolyesters are based on 4,4&#x2032;-biphenyl dicarboxylic acid, and/or 3,4&#x2032;-biphenyl dicarboxylic acid as the diacid component and may include a multifunctional acid. Copolymers may optionally base an essentially amorphous morphology, high glass transition temperature, high elongation at break, and/or high melting temperature. A method to make the copolymers controls the characteristics of the copolyester selected from one or a combination of amorphous morphology or degree of crystallinity, Tg, Tm, tensile modulus, flexural modulus, elongation at break, and so on, by selecting the proportions of the 4,4&#x2032;-biphenyl dicarboxylic acid or ester producing equivalent thereof, 3,4&#x2032;-biphenyl dicarboxylic acid or ester producing equivalent thereof, and/or the proportion of the 1,4-cyclohexanedimethanol in the diol component.

Bibenzoate copolyesters and methods to produce them

Compositions of polyamide resins containing a low level of polyamide 66 comonomer are provided, which are useful in producing blown films. A method of forming a blown film includes: extruding a polyamide copolymer to form a polyamide film. The polyamide copolymer is formed from a mixture of caprolactam and hexamethylenediamine adipate where the caprolactam comprises from 85 mol. % to 99 mol. % of the total moles of caprolactam and hexamethylenediamine adipate.
