Functionalization of low molecular weight atactic polypropylene - Part I. Spectroscopic studies
(Springer Verlag, 1999) Oktem, Z; Cetin, S; Akin-Oktem, G
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 dicumyl peroxide (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, concentrations of the functional compounds and DCP on the extent of grafting were examined.
Functionalization of low molecular weight atactic polypropylene - Part II. Thermal and molecular weight studies
(Springer, 2000) Akin-Oktem, G; Cetin, S; Oktem, Z
Number average molecular weight (M-n), intrinsic viscosity ([eta]) and glass transition temperature (T-g) of low molecular weight atactic polypropylene (APP) grafted with 4-allyl-1,2-dimethoxybenzene (DMAB), 4-allyl-2-methoxyphenol (eugenol) and 4-propenylanisole (trans-anethole) in the presence of dicumyl peroxide (DCP) at 170 degreesC were determined. The influences of reaction time, concentration and extent of grafting on M-n, [eta] and T-g of APP were examined. The data were discussed with the mechanism of grafting reactions.
