Polyamide-elastomer-mixture, useful to produce molded parts used in automotive field, comprises a partly crystalline polyamide with specific solution viscosity, elastomer, and polyamide with less solution viscosity than specific viscosity

摘要

Polyamide-elastomer-mixture comprises: (a) 30-95 wt.% of at least a partly crystalline polyamide with a solution viscosity of >= 1.75 (measured in m-cresol-solution, 0.5 wt.%, 20[deg] C); (b) 5-50 wt.% of at least an elastomer, which is produced by emulsion polymerization and subsequent spray drying of the latex produced by the emulsion polymerization; (c) optionally 0-20 wt.% of one or more polyamides with a solution viscosity of less than 1.75 (measured in m-cresol-solution, 0.5 wt.%, 20[deg] C), as well as 0-100 parts by weight of one or more additives. Independent claims are included for: (1) *a molded part obtained from the polyamide-elastomer-mixture; and (2) use of acrylonitrile-containing elastomers, which are produced by emulsion polymerization and subsequent drying of the latex obtained in the emulsion polymerization, for the production of polyamide-containing compositions.
