Organic silicon compounds

摘要

Organic silicon compounds which are expressed by the general chemical formulae (I) or (II): <IMAGE> (I) <IMAGE> (II) wherein R1 is a monovalent organic group with 1 to 8 carbon atoms; R2, R3 and R4 in each equation are independent and either a monovalent organic group with 1 to 8 carbon atoms or a siloxyl group expressed by <IMAGE> wherein R5, R6 and R7 are independent in each equation and they are a monovalent organic group with 1 to 8 carbon atoms; and a is either 0, 1 or 2. The novel organic silicon compounds possess both a polymerizable double bond and organopolysiloxane within the same molecule. These compounds are superior in their polymerizability and copolymerizability and are useful as polymer reforming agents.
