摘　　要：用苯基三甲氧基硅烷、二苯基二甲氧基硅烷水解制备了聚苯基甲氧基硅烷(PPMS),采用两种不同的方法,用PPMS对甲醛松香环氧树脂进行了改性。结果表明,化学改性方法优于物理改性方法。物理改性方法对性能的提高没有起到明显的作用,两相相容性差,固化物性能降低;化学改性方法既提高了固化物的力学性能,又提高了固化物的热性能,相容性较好。Polyphenylmethoxy Silicone(PPMS) was synthesized by way of hydrolysis-condensation of phenyltrimethoxysilone and dimethoxydiphenylsilone. Formaldehyde rosin epoxy resin was modifi ed by PPMS by two different methods. Testing results indicated that chemical modifi cation was superior to physical modifi cation as the latter did not play marked role on performance of the cured product. Because of poor compatibility of two phases between PPMS and FMRE,performance of the cured product was worse. Chemical modifi ...
