TERMINAL CLUSTER ACRYLATE SILICONES

摘要

Acrylic functional liquid polyorganosiloxane polymers having a novel block architecture which provides efficient UV or chemically initiated cure to elastomers. These polymers are characterized by one of the formulas: (AB)mC or [(AB)m]nSiR(4-n) where B is an elongated diorganosiloxane segment free of acrylic functionality; A is shorter organosiloxane segment containing a plurality of siloxane repeat units; C is A or a triorganosilyl group; R is an organo group; M is an integer of 1 or more; and n is 3 or 4.
