Synthetic method for the synthesis of silicon polyether copolymers |
摘要 |
The present invention is based on the discovery that various metal catalysts will catalyze the ring opening polymerization of epoxides to yield polyethers. The present invention therefore provides a method of making a polymeric product by ring-opening polymerization of heterocyclic epoxide monomer including the steps of preparing a mixture comprised of a catalyst; a Si-H containing compound; and at least one compound which is a heterocyclic epoxide containing monomer; and reacting the mixture at a temperature effective to promote ring-opening polymerization of the at least one compound to produce a polymeric product, preferably at room temperature. The present invention additionally provides for the silicone-polyether compositions created by this method.
