Abstract

A high melt strength resin composition includes at least a) non-functionalized polypropylene, b) at least one acrylate such as zinc diacrylate, calcium diacrylate or aluminum triacrylate in a total amount of from 0.1 to 5% by weight based on the weight of non-functionalized polypropylene, and c) at least one acid neutralizer in a total amount of from 0.005 to 5% by weight based on the total weight of the at least one acrylate. The resin composition is compounded at a processing temperature between 185° C. and 260° C. to obtain the high melt strength polypropylene.
