Low molecular weight atactic polypropylene (APP) was functionalized with 4-allyl-2-methoxyphenol (eugenol), 4-allyl-1,2-dimethoxybenzene (DMAB), 4-propenylanisole(trans-anethole), cis-2,4,5-trimethoxypropenylbenzene (#beta#-asarone) and 4-allyl-2,6-dimethoxyphenol (ADMP) in the presence of...
The reaction of ortho-, meta- and para-dimethoxybenzene with linear acyl chlorides under acid zeolite catalysis was examined. Zeolites HY with different SiO2/Al2O3 molar ratio (6, 14 and 390, respectively) were tested and their activity correlated with the acid site distribution (density, n...
