Abstract
Copolymerization of tetrafluoroethylene and ethylene was investigated in tr ichlorotrifluoroethane and trichlorofluoromethane solvents. The high solubi lity of the monomers in these solvents made polymerization under reduced pr essures possible. Trichlorofluoromethane acted as an effective chain transf er agent to regulate the molecular weight. Kinetic studies showed that bimo lecular and unimolecular termination prevailed at low and high polymer conc entrations, respectively. (C) 1999 Elsevier Science Ltd. All rights reserve d.
