摘要
采用阴离子开环聚合的方法,由含二甲基硅氧链节的环状甲基苯基硅氧烷和乙烯基双封头在碱性催化剂的作用下制备乙烯基封端甲基苯基硅油。采用核磁、红外和GPC等表征手段对其进行检测。实验具有良好的可重复性,制备的样品性能优异,质量稳定可靠,具有良好的市场应用前景。
Using methylphenyl-dimethyl mixed cyclic siloxanes as the raw material, divinyl tetramethyl disiloxane as the terminator, vinyl terminated methylphenyl silicone oil was prepared by anion polymerization. Its performance was char- acterized by 1 H-NMR, IR and GPC. The experiment had good duplication and performance of product was excellent. The product had very good market prospects.
