Free- and reversible deactivation radical (co)polymerization of isobutylene in water under environmentally benign conditions

The synthesis of a linear polyisobutylene is achieved for the first time by free radical polymerization. reaction was performed in environmentally friendly conditions, i.e., an aqueous medium using cyclodextrin solubilizer, around room temperature. This mild and straightforward polymerization resulted predominantly polymer with low dispersity. Isobutylene also copolymerized acrylamide via this assisted free-radical polymerization, leading to new poly(isobutylene-co-acrylamide) amphiphilic copolymers. feed composition copolymerization had huge effect on and, therefore, resulting copolymer's solubility. Reversible addition-fragmentation chain transfer (RAFT) isobutylene carried out PEG-based symmetrical macro agent. Poly(PEG-b-isobutylene-b-PEG) block-copolymer formed one-pot reaction. novel method opens new, benign routes produce copolymers various applications.
