FIBROUS MATERIAL FROM HOMOGENEOUS ALLOYS OF AROMATIC POLYAMIDES AND POLY-N-VINYL-PYRROLIDONE, PROCESS FOR THEIR PREPARATION AND APPLICATION

摘要

Fibrous materials made of synthetic polymers, characterised in that the synthetic polymer is a homogeneous alloy consisting essentially of alpha ) poly-N-vinylpyrrolidone (PVP) and beta ) at least one homo- or copolyaramid having at least one recurring structural unit of formula (I) where E<1> and E<2> are identical or different and denote two-valent aromatic or aliphatic radicals.
