Functionalization of low molecular weight atactic polypropylene - Part I. Spectroscopic studies

Low molecular weight atactic polypropylene (APP) was functionalized with 4- allyl-2-methoxyphenol (eugenol), 4-allyl-1,2-dimethoxybenzene (DMAB), 4-pro penylanisole(trans-anethole), cis-2,4,5-trimethoxypropenylbenzene (beta-asa rone) and 4-allyl-2,6-dimethoxyphenol (ADMP) in the presence of dicumyl per oxide (DCP) at 170 degrees C. Amount of grafted eugenol, DMAB and anethole on APP and characterization of the products were carried by UV-VIS and FTIR spectroscopies respectively. The effects of the reaction time, concentrati ons of the functional compounds and DCP on the extent of grafting were exam ined.
