Polyamide melt adhesives

摘要

Polyamides and polyesteramides having melt viscosities from 25 to 600 Pa.s at 220 DEG C. and useful as melt adhesives for textiles are disclosed, which materials are condensation products formed between (a) a dimerized fatty acid component containing at least 70 percent of dimeric acid; (b) a C6-C13 aliphatic straight-chain co-dicarboxylic acid; (c) a C6-C12 aliphatic straight-chain diprimary diamine; and (d) caprolactam and/or epsilon -amincaproic acid; the polyesteramides additionally contain a further component (e) which is caprolactone and/or epsilon -hydroxycaproic acid.
