Abstract
New Ionomer compositions which have improved moldability and improved high temperature behavior are based on ionomer polymerized at normal pressures but lower than normal temperatures. The compositions may be blends with standard ionomer, particularly if the low-temperature-prepared ionomer is prepared at very low temperatures which reduces productivity compared with standard ionomer, or useful alone when prepared at intermediate temperatures.
