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) IMAGE where E1 and E2 are identical or different and denote two-valent aromatic or aliphatic radicals.
