摘要
Abstract
The solvent resistance of cast films based on homopolymer polypropylene,impact copolymer polypropylene,binary random copolymer polypropylene,and ternary random copolymer polypropylene was systematically investigated.By combining solvent resistance studies with analyses of crystallinity and miscibility,it was found that enhancing crystallinity or increasing comonomer content directly improves the film's electrolyte resistance.Therefore,homopolymer polypropylene and impact copolymer polypropylene demonstrate superior electrolyte resistance,higher morphological stability,and greater mechanical property retention rates compared to random copolymer polypropylenes,attributed to their high crystallinity and high comonomer content.关键词
