Grafting of 2-hydroxyethyl methacrylate (2-HEMA) on isotactic polypropylene (IPP) and in situ chlorinated polypropylene (CPP) by free radical process was carried out at 110 degrees C using toluene as solvent. Various conditions for grafting were optimized. The maximum percent of grafting of S-HEMA achieved on IPP was 3.6%, whereas that on in situ CPP was 8.7%. The products were characterized by Fourier transform infrared spectroscopy and thermal and contact angle measurements.
