Abstract:
A thermoplastic composition comprising a matrix and a resilience-modifying compound, wherein:the matrix comprises a mixture of at least a first thermoplastic and a second thermoplastic,the first thermoplastic comprises a copolymer of:(i) .epsilon.-caprolactam and(ii) at least one of an amino acid comprising at least 9 carbon atoms, a lactam corresponding to the amino acid comprising at least 9 carbon atoms, or a mixture of hexamethylenediamine with a diacid comprising at least 9 carbon atoms having a ratio of weight % of .epsilon.-caprolactam to weight % hexamethylenediamine and diacid mixture of 4-9,the second thermoplastic comprises a polyamide or copolyamide of monomers comprising less than 9 carbon atoms, and the content of the second thermoplastic in the matrix is 40-80 weight % of the matrix and greater than 20 weight % of the overall composition, and the resilience-improving compound comprising 20-50 weight % of the overall composition.
