摘要：
Vinyl chloride/isobutyl vinyl ether (VC/IBVE) copolymer was synthesized by batch emulsion polymerization process, using Na2SO3/(NH4)2 S2O8/CuSO4 as the initiator system and sodium dodecyl sulfonate (SDS) as the emulsifier. It showed that the polymerization rate and intrinsic viscosity of copolymer decreased as the feed mass fraction of IBVE increased. The variation of copolymer composition was not significant when polymerization was less than 70%. The polymerization rate increased with the increase of polymerization temperature and the concentration of initiator system, and changed no more as the concentration of SDS varied. The intrinsic viscosity decreased with the increase of polymerization temperature, and had no obvious change when the concentrations of initiator system and SDS were varied.
