| Abstract: | In this paper,the emulsion polymerization of VC in the presence of PVA is stu-died,the solid content of the emulsion,radius of the emulsion particles,graft percentage,degree of polymerization and various stability of the emulsion are determined.The effect ofinitiator system and its quantity used,reaction temperature,various emulsion agent as wellas the cross linking agent on the emulsion polymerization and the properties of the emul-sion are investigated.Based on these results,the optimal preparation conditions of the PVCemulsion which is suitable for spinning PVA/PVC blend fibre are obtained.Furthermore,the PVA/PVC graft copolymer is isolated by using dissolving method.By using elementanalysis and infrared absorption spectrum the structure of the graft copolymer is probed. |
