摘要

A process for producing a silicone polymer, characterized by hydrolyzing/condensation-polymerizing one or more silane compounds comprising 35 to 100 mol% silane compound represented by the formula (I): R'm(H)kSiX4-(m+k)[wherein X represents a group capable of undergoing hydrolysis and polycondensation, such as halogeno, e.g., chlorine or bromine, or -OR (wherein R represents C1-4 alkyl or C1-4 alkylcarbonyl); R' represents a nonreactive group such as C1-4 alkyl or aryl, e.g., phenyl; and k is 1 or 2 and m is 0 or 1, provided that m+k is 1 or 2] and subjecting the resultant reaction product to hydrosilylation with a hydrosilylating agent.
