摘　　要：在苯乙烯 -丙烯酸酯乳液共聚反应后期 ,加入少量乙烯基硅氧烷 ,制得改性苯丙乳液 ,通过红外光谱初步确定聚合物结构。研究了反应温度、反应时间、有机硅加入方式、乳化剂用量等因素对反应进程。The titled modified styrene-acrylic emulsion has been prepared by incorporation of small amount of vinyl siloxane at the late stage of copolymerization of styrene-acrylic emulsion. The final polymer structure is determined by IR spectrometry. The influences of reaction temperature and time, incorporation procedure of vinyl siloxane, and dosage of emulsifier on reaction, stability of emulsion and coating film properties were discussed.
