| 摘要 |
The invention relates to a flexible polyamide composition containing at least 50 parts by weight of non-cross-linked rubber per 50 parts by weight of polyamide and the production thereof. The polyamide has a molecular weight such that the melt viscosity at the processing temperature is at most 300 Pa.s, preferably at most 200 Pa.s. The rubber's Mooney viscosity is at least 40, most preferable is a rubber with a Mooney viscosity of at least 60. The rubber has been functionalized. Preferably a combination of a functionalized and a non-functionalized rubber is used. The rubber particles in the polyamide matrix have a particle size of at most 5¼ m, preferably at most 3¼ m.
