Abstract
A sequential catalysis of the ring opening polymerization of cyclic organosiloxanes using a base catalyst that can be neutralized by a subsequent redistribution and condensation Lewis acid catalyst, preferably a phosphonitrilic compound, permits the rapid synthesis of functionalized and poly-functionalized silicone copolymers such as alkenyl hydride copolymers, a new composition of matter, which is a one component curable silicone by means of hydrosilylation or peroxide initiated free radical polymerization. The alkenyl hydride copolymer is formulated into a curable composition, emulsified and coated onto an automobile airbag and subsequently cured.
