Abstract
Ionomeric compositions which are blends of a first ethylene/acid copolymer polymerized at low temperatures and normal pressures, and a highly neutralized second ethylene/acid copolymer, polymerized at normal polymerization temperatures and pressures but having a high melt index, above 80 g/10 min., in the parent acid copolymer and also a high melt index, above 3.0 g/10 min., in the resulting neutralized ionomer, have both improved high temperature mechanical properties and improved melt processability. Alternatively, the first and second acid copolymers may be blended and neutralized in the same melt process step, or first melt blended, and then neutralized in a subsequent melt process step.
