ABSTRACT:
Higher yields of graft copolymer occur when a catalytic amount of base is present during the grafting reaction of a polyamide and a polyglutarimide. The resulting blends of ungrafted polyamide and polyglutarimide with higher graft-copolymer content, the graft copolymer being a polyamide-grafted poly(glutarimide)ionomer, exhibit improved toughness and clarity.
