Thermoplastic reinforcing adhesives and substrates coated therewith

摘要

Copolyamides derived from mixed acids (a polymeric fatty acid and short-chain dibasic acid) and mixed amines (a polyoxyalkylene diamine and a short-chain diamine) are provided. These thermoplastic resin compositions are excellent reinforcing adhesives for flexible substrates and are particularly useful as box-toe construction resins.
