ABSTRACT:
Copolyamides derived from a mixture of short-chain and long-chain saturated aliphatic dicarboxylic acids, piperazine and a polyoxyalkylene diamine are excellent hot melt adhesives useful with a variety of substrates. These thermoplastic copolyamide resins are particularly useful adhesives for vinyl materials and are resistant to creep.
