Thermoplastic polyamide based upon dimerized fatty acid and polyether
polyamine
摘要:
This invention is directed to thermoplastic polyamides and the preparation thereof. The thermoplastic polyamides, which are prepared by condensing (a) dimerized higher fatty acids and (b) monomeric fatty acids with (c) polyether diamines and (d) aliphatic or cycloaliphatic diamines, are useful in melt adhesive compositions.
