Abstract: The polypropylene was modified with solid surface modification method. The effects of reaction conditions on the gel fraction in the system were discussed. IR, WAXD, DSCand DMA were used to characterize the influences of modification on the crystallizability of polypropylene. The results show a surface-to-core modification process.

Key words: Polypropylene, Gel fraction, Solid surface modification, Crystallizability
