Abstract
Investigated was the effect of the crucial polymerization conditions such as methyl acrylate(MA) mole fraction in feed, polymerization temperature and time on Atom Radical Transfer Polymerization(ATRP) behavior of styrene and methyl acrylate(MA). As MA mole fraction in feed increased, molecular weight(MW) of the resulting copolymer increased. At polymerization time of 3 hrs the composition of MA in the resulting copolymer was shown to have a linear relationship with the mole fraction of MA in feed. MW was increased and the composition of MA in copolymer was decreased as the polymerization time increased, showing the characteristics of ATRP. MW was also increased as polymerization temperature increased, and the composition of MA in copolymer was shown to be increased drastically at polymerization temperature of $110^{\circ}C$.
