Abstract
Silicone polyether copolymers are disclosed having the average formula E-B-[AB]n-E where E is an organofunctional endblocking group, B is a diorganopolysiloxane, A is a divalent organic group comprising at least one polyether group, and n is ≧1. The silicone polyether copolymers having an amine functional endblocking group are useful in the treatment of textiles and fibers.
