Thermoplastic elastomeric polyetheresterimides

摘要

Thermoplastic elastomeric polyetheresterimides comprising a multiplicity of long chain ester imide units represented by the formula <IMAGE> and short chain esterimide units represented by the formula <IMAGE> where G is a divalent radical remaining after the removal of terminal hydroxyl groups from a poly(alkylene oxide) glycol having a number average molecular weight of about 400-4000; D is a divalent radical remaining after removal of hydroxyl groups from a diol having a molecular weight less than about 300, and Q is a divalent radical remaining after removal of an amino group and a carboxyl group from a aliphatic primary amino acid having a molecular weight of less than 250; with the proviso that from about 2 to 10 of said short chain esterimide units are present for each of said long chain esterimide units.
