发明名称 Ionomers having improved low temperature properties
摘要 Ionomers of ethylene, unsaturated carboxylic acid and softening comonomer, e.g. alkyl acrylate and/or alkyl vinyl ether having improved low temperature properties are obtained by direct or graft copolymerization at a temperature of from about 100 DEG to about 200 DEG C., followed by neutralization of the carboxylic acid groups with metal ions, such ionomers being characterized by a low level of chain branching of up to about 5.5 chain branches/1000 backbone methylene units.
