【摘要】：分别对甲基苯基混合环体体系、八苯基环体体系通过开环聚合所制备的高黏度苯甲基硅油性能进行了研究。结果表明,随着封端剂用量的增加,苯甲基硅油的黏度降低,封端剂的合理使用能有效控制苯甲基硅油的黏度;随着八甲基环四硅氧烷(D4)用量的增加,苯甲基硅油的折光率下降。由八苯基环体体系制备出的苯甲基硅油黏度受温度的影响小于混合环体体系,耐热性在质量损失率为10%时优于混合环体体系。
[Abstract]:The properties of high viscosity benzyl silicone oil prepared by ring-opening polymerization of methyl phenyl mixed ring system and octaphenyl ring system were studied respectively. The results showed that the viscosity of benzene methyl silicone oil decreased with the increase of the content of entrapment agent. The reasonable use of the entrapment can effectively control the viscosity of phenylmethyl silicone oil, and with the increase of octomethylcyclotetrasiloxane (D4) content, The viscosity of benzyl silicone oil prepared from octaphenyl ring system is less affected by temperature than that of mixed ring system, and the heat resistance is better than that of mixed ring system when the mass loss rate is 10.
