Polyamide formed by polymerization of carboxylic diacid/diamine monomer in presence of multifunctional compound e.g. 2,2,6,6-tetra-(beta-carboxyethyl)cyclohexanone and monofunctional compound e.g. benzoic acid useful to make molded article

摘要

Polyamide obtained by polymerization of carboxylic diacid and diamine monomer or their salts in the presence of a multifunctional compound (0.05-0.5 mol.%) having at least three functional groups (X1) and a monofunctional compound (0.5-2 mol.%) having a functional group (X2). The functional groups (X1) and (X2) are carboxylic acids or amine groups. Independent claims are included for: (1) a composition comprising the polyamide present as a thermoplastic polymer or as an additive; and (2) a molded article obtained by injection-, injection/blow-, extrusion-, extrusion blow molding of the composition.
