Homopolymerization and copolymerization of the ester made of rosin and glycidyl methacrylate
摘要
Abstract
Arosin ester (RG) was made from rosin and glycidyl methacrylate (GMA). Radical homopolymerization of RG and copolymerization with styrene (St) in solution were carried out. The effects of reaction conditions,including raw material ratio,reaction temperature,initiator type and amount,on the polymerization were investigated. The homopolymer PRG and the copolymer P(RG-co-St) were characterized by Fourier transfer infrared spectrometer (FT-IR),thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC),respectively. The results showed that PRG and P (RG-co-St) were synthesized successfully,and AIBN was the best initiator for homopolymerization and copolymerization. With the increase of reaction temperature,the molecular weight (Mn) of the copolymer increased and the molecular weight distribution (MWD) was narrowed. With the increase of St loaded,theMn of copolymer decreased but MWD was broadened. In addition, the copolymer had the similar initial decomposition temperature and higher the-most-decomposition- temperature,and the copolymer exhibited higher glass transition temperature than the homopolymer.关键词
