摘要
用Ｆｉｍｅｍａｎ－Ｒｏｓｓ法处理数据，测定了乙烯基聚硅氧烷（ＳＶ）与苯乙烯（ＳＴ）、甲基丙烯酸甲酯（ＭＭＡ）和甲基丙烯酸正丁酯（ｎ－ＢＭＡ）的共聚反应的竞聚率，结果为ｒＳＴ＝１．４５和ｒＳＶ＝１．０８，ｒＭＭＡ＝０．７８和ｒＳＶ＝２．０１，ｒｎ－ＢＭＡ＝０．４６和ｒＳＶ＝３．４９．以含ＳＶ的乳液作为种子进行烯类单体的乳液聚合，单体和ＳＶ共聚反应对复合粒子的形态有很大影响。
The copolymerization reactivity ratios of vinyl-containing polysiloxane(SV) with styrene(ST),methyl methacrylate(MMA) or n-butyl methacrylate(BMA) were measured using Fineman-Ross method,and the results were:rst =1.45 and rsv =1.08 for ST-SV,rMMA =0.78 and rsv=2.01 for MMA-SV,rn-BMA =0.46 and rsv =3.49 for BMA-SV,respectively.The reactivity ratios between vinyl-containing polysiloxane and vinyl monomers had a strong effect on the morphology of the particles prepared by the seeded emulsion polymerization.
