PLASMA-INITIATED POLYMERIZATION AND BLOCK GOPOL- YMERIZATION OF SODIUM SULFOHEXYL METHACRYLATE
甲基丙烯酸己磺酸钠的等离子体射发聚合与嵌段共聚合

Very thick slurry of sodium sulfohexyl methacrylate (SSHMA) with little amount of water was plasma-initiated and polymerized. The mechanism and kinetics of plasma-initiated polymerization of SSHMA were preliminarily studied. The existence of macromolecular "living" chains were ascertained by experiments. Thus, SSHMA-acrylic acid block copolymers were obtained by adding acrylic acid to livingSSHMA segments. The ESR results suggest that propagating radicals CH2C(CH3)CO-O(CH2)6SO3Na might be present in the SSHMA system initiated by plasma. It was found that no"living"chains were present in the SSHMA system initiated by either UV light or radical initiators under the same conditions.
