摘　　要：合成了偏氯乙烯 (VDC) -氯乙烯 (VC)悬浮共聚树脂 ,研究了聚合时间 分散剂用量和搅拌器转速等对共聚树脂颗粒特性的影响。结果表明 :树脂粒径随聚合时间延长而增大 ,并趋于定值 ;增加分散剂用量 ,粒径先减小后增大 ,当分散剂用量为 0 12 %时 ,平均粒径最小 ;平均粒径随搅拌器转速提高呈马鞍形变化 ,在 13 0r/min时粒径最小 。Vinylidene chlorid e(VDC)-vinyl chloride(VC) suspension cop olymers were synthesized,and the effects of reaction time,dispersing agent and a gitation speed on the particle diameter and distribution of VDC-VC suspension co polymers were investigated The results showed the average particle diameter inc reased with the increase of the reaction time,and tended to be smooth;with the i ncrease of the dispersing agent content( DAC),the average particle diameter decre ased when DAC was small and then increas ed as DAC was above the critical value(0 12wt%) The change of average particle diameter with agitation speed was in the shape of saddle, the critical agitation speed corresponding to smallest average particle diameter was about 130r/min P article morphology was so good as Wuyu r esin imported from Japan
