摘要:
The invention relates to antistatic polyamide compositions comprising a polyamide and as an antistatic agent from 0.1 to 20%, preferably from 1.5 to 15%, by weight based on the total weight of the composition of urethanes with ether groups. The urethanes with ether groups are stable in melts of aliphatic polyamides for prolonged periods at temperatures of up to about 300.degree. C. and filaments and fibers of such polyamides or woven fabrics, knitted fabrics, non-woven or pile fabrics produced from these filaments or fibers show outstanding antistatic properties.

The invention relates to a copolymer comprising at least 40% by weight of copolymerized acrylonitrile and from 0.5 to 10% by weight of at least one copolymerized unsaturated ester of acetoacetic acid corresponding to the general formula:CH.sub.3 --CO--CH.sub.2 --COO--R--CR'.dbd.CH.sub.2and, optionally, at least one other copolymerized comonomer.
摘要:
The invention relates to a copolymer comprising at least 40% by weight of copolymerized acrylonitrile, from 0.5 to 40% by weight of at least one copolymerized aceto acetate of a mono (meth) acrylate of an aliphatic diol containing from 2 to 8 carbon atoms and, optionally, at least one other copolymerized comonomer.
摘要:
Mouldings having a matrix reinforced by polyacrylonitrile fibers, or organic or inorganic material show improved properties, especially strength if the fibers have previously been treated with a mineral tanning substance.
