以羟基封端聚砜齐聚物(简称聚砜齐聚物)和二甲胺封端聚二甲基硅氧烷齐聚物(简称聚硅氧烷齐聚物)的缩聚,可得到聚砜-聚二甲基硅氧烷嵌段共聚物。改变两种齐聚物的分子量,可以合成出具有从塑料到橡胶性能的各种嵌段共聚物。
Polycondensation of hydroxyl-terminated polysulfone oligomers (referred to as polysulfone oligomers) and dimethylamine-terminated polydimethylsiloxane oligomers (referred to as polysiloxane oligomers) yields polysulfones Polydimethylsiloxane block copolymer. By varying the molecular weights of the two oligomers, various block copolymers with plastic to rubber properties can be synthesized.
