ABSTRACT:
The crystallization from the melt of an isotactic butene-1 homopolymer composition, isotactic butene-1-ethylene copolymer or isotactic butene-1-propylene copolymer composition is promoted by adding a small amount of stearamide and high density polyethylene as nucleating agents. The two nucleating agents cooperate in a synergistic fashion, resulting in much faster processing rates.
