摘要: Radical copolymerization of divinyl monomers in the presence chain transfer agents leads to soluble hyperbranched polymers. In this work, poly(poly(ethylene glycol) methyl ether methacrylate) (PPEGMA) with degradable cross-linker branch points derived from glucarodilactone methacrylate was prepared via reversible addition–fragmentation (RAFT) polymerization provide insight into hyperbranch formation during copolymerizations multiolefinic compounds. The number-average molecular weight polymers increased nonlinearly monomer conversion, implying that incorporation led branching and a rapid increase at high conversion. degree varied by controlling feed ratio agent. Hydrolytic degradation sugar-derived dilactone examined under acidic, neutral, basic aqueous conditions. To fundamental into...
