摘　　要：介绍粉末氯丁橡胶(PCR)的制备方法及研究进展。国外PCR制备方法的专利较多,我国PCR制备和应用处于起步阶段。PCR的制备方法主要有低温干燥法、喷雾干燥法、表面卤化法、酸化絮凝法和逆凝聚法等。PCR解决了块状氯丁橡胶(CR)合成工艺中易形成焦烧粒子的问题,拓展了CR应用领域。与块状CR相比,PCR加工中可免除切胶工序,提高加工效率,大幅降低生产成本;胶料焦烧倾向降低,配合剂分散更均匀,制品性能更稳定。The preparation method and research progress of powdered polychloroprene rubber（PCR） were presented. PCR preparation methods were disclosed in many foreign patents,while the development of PCR preparation and application in China were still in the initial stage. PCR preparation methods mainly included low temperature drying method,spray drying method,surface halogenation method,acidification flocculation method and reverse coagulation method. PCR solved the problem of easy formation of scorched particles in the block polychloroprene rubber（CR） synthesis process,and extended the application field of CR. Compared with the block CR,application of PCR eliminated cutting process,improved processing efficiency,significantly reduced production cost,reduced rubber scorch issue,improved additive dispersion and consistency of product performance.
