Hydrophilic Silicone Copolymers Useful In Carbon Fiber Production

摘要

Robust oiling agent compositions for use in preparing carbon fibers from acrylic polymer carbon fiber precursors contain at least one silicone copolymer minimally containing an organopolysiloxane moiety, a polyoxyalkylene polyether moiety, and at least one internal or terminal urea or urethane group.
