摘　　要：阐述了MBS接枝胶乳”粒子设计”的依据,在已有MBS胶乳合成小试技术和SBR胶乳合成中试研究的基础上,进行了MBS胶乳合成技术的中试研究,着重研究了甲基丙烯酸甲酯和苯乙烯的接枝顺序、接枝率和橡胶相含量等对PVC/MBS抗冲性能的影响,以及接枝聚合反应温度对MBS树脂接枝率的影响,并将中试试验结果与小试结果进行了对比,为5 000 t/a MBS生产装置提供了设计依据。The theory basis of ＂particle design＂ of MBS grafting latex was described, pilotscale experiments of synthesis of MBS Latex were carried out basing on the recipe of small scale experiment of MBS latex and pilolscale experiment results of SBR latex, the effects of grafting sequence of methyl methaerylate and slyrene, grafting ratio and rubber phase content on impact strength of PVC/MBS and grafting polymerization temperature on grafting ratio of MBS resin were investigated. The pilotscale recipe and process conditions were delermined by comparing the pilotscale results with small-scale resmts. These results provided basis to the design of 5 000 t/a MBS resin production plant.
