RAFT Polymerization and Characterization of Rosin Derived Monomer
摘要
Abstract
Rosin derived monomer blend was synthesized by chloridization and esterification in turn, and characterized by FT-IR, GC/MS and 13C NMR, respectively. Rosin derived monomer blend, reversible addition-fragmentation chain transfer ( RAFT) agent CDB and initiator AIBN with molar ratio of 100∶1∶0. 1 were then used to perform RAFT polymerization. In order to further investigate the RAFT polymerization of rosin derived monomer blend, high purity dehydroabietic acid was also employed to perform RAFT polymerization. The results showed that dehydroabietic acid derived monomer accounted for 14. 3 % in rosin derived monomer, and the RAFT polymerization of dehydroabietic acid derived monomer was well controlled and achieved a well-defined dehydroabietic acid based polymer with polydispersity index ( PDI) of 1. 28. And PDI of rosin derived monomer based polymer was 1. 85 which was relative higher than that of dehydroabietic acid based polymer. However, its polymer structure was still regarded well-defined. The rosin based polymer obtained by RAFT polymerization was also a novel Marco-RAFT agent, which could be used as RAFT agent for next step RAFT polymerization with purpose of polymer chain extension. Additionally, the synthesized rosin based polymers were all demonstrated with good thermal stability, temperature of the mass loss at 10% and maximum decomposing temperature was 250℃ and 350℃, respectively.关键词
