Kinetics of methyl methacrylate reversible addition-fragmentation chain transfer polymerization
摘要
Abstract
Methyl methacrylate(MMA)was an important ingredient for different structures and properties of copolymers.In order to study MMA reversible addition-fragmentation chain transfer(RAFT)polymerization kinetics,bulk and miniemulsion for MMA polymerization were performed with 2-cyanoprop-2-yl dithiobenzoate(CPDB)as RAFT agent.The conversion decreased with increasing CPDB concentration in bulk and miniemulsion system,and the retardation was more obvious in miniemulsion than in bulk system.The linear relationship between the polymerization index -ln(1-x)and the polymerization time was good,which has the controlled /"living" polymerization characteristics.The Molucular weight of PMMA in bulk and miniemulsion systems increased linearly,and its distribution became much narrower along with the increasing of conversion,when CPDB concentration increased.Moreover,the particle size increased with CPDB concentration increaseing in miniemulsion,and the distribution became much broader.关键词
