Material comprising a polyamide, a polymer having polyamide and polyether blocks and a functionalized polyolefin, and film and object obtained therefrom

摘要

A material is provided comprising: (a) a polyamide; (b) a polymer having PA blocks and polyether PEG blocks; (c) optionally a polyolefin; (d) a functionalized polyolefin; the various constituents being present in amounts by weight, a, b, c and d such that: a>0; b>0; c+d>0; a+b+c+d=100; with a/b>0.2; (a+b)/(c+d)>1; and b/(a+b+c+d)<0.5. A film which is non-porous but breathable, i.e. porous to water vapor but not to water, and an antistatic object obtained from this material are also provided.
