A novel rosin derived ATRP initiator((2-bromoisobutyric) hydroxyethyl ester of dehydroabietic acid, 2-BriBEDA) was first designed from dehydroabietic(DA), and was subsequently employed to initiate two kinds of monomers, namely methyl methacrylate (MMA) and lauryl methacrylate (LMA) through ATRP to prepare the rosin initiated copolymer (DA-P(LMA-co-MMA)). Kinetic studies showed that polymerizations of MMA and LMA with 2-BriBHDA were living and controlled. DA-P(LMA-co-MMA) with various feed molar ratios were prepared to investigate the effect of DA on the polymer properties. It was found that these rosin initiated copolymers have improved thermal stability, stress and elastic recovery ability in contrast to the neat copolymers (P(LMA-co-MMA)) which were without DA parts. Additionally, UV-Visible Spectrophotometer analysis indicated that UV absorption capability of DA has been imparted to these rosin initiated copolymers. The surface of the rosin initiated copolymer turned to be more roughness owing to the existence of DA was confirmed by AFM.
