FORMMASSEN AUF BASIS VON HOCHMOLEKULAREN POLY(ETHERESTERAMIDEN)

摘要

Improved molding compositions based on high-molecular polyether ester amides are obtained by heating at 180 DEG -250 DEG C. a melt containing a mixture of A. a polyether ester amide having a relative solution viscosity eta rel of at least 1.5; and B. 0.05-1.5 parts by weight, based on 100 parts by weight of the molding composition, of a cyclic, trimerized isophorone diisocyanate or an oligomer thereof having a degree of oligomerization of 2-5 and an isocyanate functionality of 3-7.
