A process for producing a silicone polymer comprising a step of subjecting, to hydrolysis and polycondensation reaction, a silane compound mixture containing 35 to 100% by mol of a silane compound represented by the general formula (I):R'(H)SiX&#x2003;&#x2003;(I)(wherein X is a hydrolysable and polycondensable group, e.g., a halogen atom (e.g., chlorine or bromine) or &#x2014;OR; R is an alkyl group of 1 to 4 carbon atoms or an alkyl carbonyl group of 1 to 4 carbon atoms; R&#x2032; is a non-reactive group, e.g., an alkyl group of 1 to 4 carbon atoms or an aryl group (e.g., a phenyl group); 'k' is 1 or 2; 'm' is 0 or 1; and &#x201c;m+k&#x201d; is 1 or 2), and further subjecting the resultant product to hydrosilylation reaction with a hydrosilylation agent.

There is here disclosed a thermosetting resin composition containing, as essential components, (a) an epoxy resin, (b) a curing agent, and (c) a silicone polymer having a bifunctional siloxane unit represented by the formula R SiO (wherein R is the same or a different organic group) in the molecule.

Thermosetting resin composition and process for producing the same

A clutch driven plate comprising a clutch facing plate molded from a clutch facing material comprising a fiber, a binder, and a friction modifier and a back-up plate carrying the clutch facing plate, wherein a number of dimples are formed on the surface of the clutch facing plate. The clutch driven plate is obtainable by thermo-compression molding a back-up plate and a clutch facing material comprising a fiber, a binder, and a friction modifier to integrate the plate and clutch facing material into one body.
