Abstract
A curable composition includes the following: (A) a polymer having an average unit formula (I′): [(R″)2SiO2/2]a″[(CH2═CH)(R″)2SiO1/2]b″[R″SiO3/2]c″[O1/2Si(R″)2(CH2CH2)(R″)2SiO1/2]e″; (B) a branched organopolysiloxane having an average unit formula (VI) (R4SiO3/2)x(SiO4/2)y[(R8)3SiO1/2]1-x-y; (C) an organopolysiloxane having an average unit formula (II) being capped with H: (R52SiO2/2)f(R63SiO1/2)g(R7SiO3/2)h(SiO4/2)i(CH2CH2)j; and (D) a catalyst, wherein R″, R4 to R8, x, y, a″ to c″, e″ and f to j are as defined in the specification.
