Abstract
A diorganopolysiloxane in which a polymerizable functional group is present at one (or both) molecule chain ends and in which an arbitrary group is present at the other end can be easily synthesized. The synthesis involves the opening of a cyclotrisiloxane using an alkali metal silanolate which bears the polymerizable functional group, followed by a capping reaction. The resulting diorganopolysiloxane can be used effectively as a feed material for manufacturing silicone rubbers, feed material for manufacturing novel grafted organopolysiloxanes, comonomer components for resins other than organopolysiloxanes or plastics, etc.
