ABSTRACT:
A composition comprising(A) polycycloolefin-functional polysiloxane represented by the following average compositional formula (1)wherein R1is a monovalent organic group which does not have an unsaturated bond and may be different from each other, k is the number of 0 or larger, n is the number of from 0.01 to less than 4, m is the number of from 0 to less than 4, provided that the sum of m and n is larger than 0 and less than 4,(B) a siloxane having an SiH bond represented by the following average compositional formula (2) in such an amount that a molar ratio of the SiH bond to the unsaturated bond in the component (A) ranges from 0.1 to 10,in-line-formulae description="In-line Formulae" end="lead"?HSiR2aO(4-a)/2 (2)in-line-formulae description="In-line Formulae" end="tail"?wherein R2is a monovalent organic group and a is the number larger than 0 and less than 4, and(C) an addition reaction catalyst in a catalytic amount.
