AMPHIPHILIC RESIN-LINEAR ORGANOSILOXANE BLOCK COPOLYMERS

摘要

Amphiphilic organosiloxane block copolymers and methods for making them are disclosed. The compositions incorporate an amphiphilic“linear”segment with a“resinous”segment. For example, a polyether (A) modified PDMS (B) with (AB)n architecture and polydiorganosiloxane with Si—H end-groups can be reacted with a phenyl silsesquioxane resin bearing vinyl functionality to form an amphiphilic resin-linear copolymer.
