摘 要：
采用水解缩聚法制备了含PhSiO_(3/2)、MePhSiO_(2/2)和SiO_(4/2)链节的4种不同结构的苯基硅树脂,以紫外吸收光度法在263 nm测定了产物的苯基浓度,并对苯基浓度与折光率的关系进行了研究.结果表明:苯基硅树脂的折光率主要与苯基浓度有关,与其它基团如甲基、乙烯基等的浓度关系不大.忽略其它基团的影响,苯基硅树脂的折光率与苯基浓度符合关系式:n_D=1.419 94+0.021 08 M(Ph).

摘 要：
Four kinds of phenyl silicone resin with PhSiO_(3/2),MePhSiO_(2/2),and SiO_(4/2) unit were prepared through hydrolysis-condensation reaction,and the phenyl group content was determined by ultraviolet absorption spectrophotometry at 263 nm,and the relationship between the phenyl content and the reflective index was studied. The results showed that the reflective index of the phenyl silicone resin was mainly related with the content of phenyl group,and had little relation with the content of other groups such as methyl and vinyl group. Ignored the effect of other groups relationship between the reflective index of the phenyl silicone resin and the phenyl content agreed with the following formula: n_D= 1. 419 94 + 0. 02108M( Ph).
