摘　　要：从单体配比和SBR胶乳粒径对PVC/MBS合金抗冲性能和透光率的影响方面详细阐述了MBS接枝用SBR胶乳“粒子设计”的依据;在小试配方的基础上进行了SBR胶乳的中试试验,着重研究了SBR胶乳聚合过程和乳化剂用量、反应温度及搅拌速度等对SBR胶乳粒径和体系稳定性的影响,并将SBR胶乳中试结果与小试结果进行了对比,确定了中试配方和工艺条件,为5 000 t/a MBS生产装置的设计提供了依据。The theory basis of ＂particle design＂ for SBR latex in MBS graft polymerization was described from the aspect of effects of monomer ratio and particle size of SBR latex on impact strength and light transparency of PVC/MBS. Polymerization process and the effect of the amount of emulsifier, reaction temperature and stirrer speed on particle size and the polymerization stability of SBR latex were investigated in pilotscale synthesis of SBR latex. The pilotscale recipe and process conditions were determined by comparing the pilotscale results with small-scale results, These results provided basis to the design of 5 （100t/ a MBS resin plant.
