ABSTRACT:
A resin composition which comprises:
(A) from about 99.5 to about 70 percent by weight, based on the total weight of components (A) and (B), of a poly(arylene sulfide) having a melt viscosity of from about 300 to about 8,000 poise at 1,200 sec.sup.-1 and 310.degree. C.;
(B) from about 0.5 to about 30 percent by weight, based on the total weight of components (A) and (B), of a substantially non-functionalized, emulsion cured silicone rubber which is the condensation product of (i) an organopolysiloxane having at least two active hydrogen functional groups per molecule, and (ii) an organohydrogenpolysiloxane having at least two silicon-bonded hydrogen atoms per molecule, said silicone rubber being melt dispersable with the poly(arylene sulfide); and
(C) from about 0.1 to about 2.0 parts by weight, based on 100 parts by weight of components (A), (B) and (C) combined, of an aminosilane, wherein said composition has been prepared by combining components B and C with component A in the absence of a dispersion medium.
