Abstract
Partially grafted flexible thermoplastic compositions formed by melt blending under high shear, a thermoplastic material which does not contain available graft sites, said thermoplastic material being at least one continuous phase of the composition, an ethylene copolymer containing an unsaturated mono-carboxylic acid, and a polymeric grafting agent having reactive groups capable of reacting with the mono-carboxylic acid in the ethylene copolymer and with the available graft sites in the thermoplastic material.
