摘要：

A surface functionalizaion polypropylene was prepared by entrapment a copolymer of polypropylene-grafted-poly(ethylene glycol) into polypropylene. The effects of structure of copolymer, contact dies, and content of modifiers were studied. The results of attenuated total reflection infrared spectroscopy(ATR-FTIR) and contact angle measurements indicated that PP-g-PEG could preferably diffuse onto the surface and effectively increase the hydrophilicity of PP. PPw-g-PEG with lower PEG contents, lower molecular weight of PPw and PEG had better selective enrichment on the surface of PP blend film. By grafting of PEG-OH onto the MPP, PP macromolecular surface modifier with better solvent-resistance than that of PEG can be achieved. (C) 2009 Wiley Periodicals, Inc.
