    摘要： A composition which is heat curable to give an elastomer of improved properties comprising(a) an organopolysiloxane polymer having a viscosity of 1,000,000 to 200,000 mPas at 25.degree. C. and comprising the structural unit ##EQU1## wherein R is a hydrocarbon radical or a halohydrocarbon radical, anda is between about 1.95 and 2.01,(b) a polycarbodiimide-polysiloxane copolymer comprising a polysiloxane continuous liquid phase containing a discontinuous phase of finely dispersed polycarbodiimide particles produced by condensing a diisocyanate in the polysiloxane,(c) a curing catalyst, and(d) a filler,the polycarbodiimide comprising about 0.1 to 80% by weight of (a) plus (b). Upon curing, the permanent set of the elastomer is reduced and/or the resistance to hydrolytic degradation is improved.
