PURPOSE: To obtain a composition which can be cured into a crosslinked solid polyorganosiloxane excellent in thermal properties by mixing a plurality of specified silicone prepolymers with a curing catalyst. ;CONSTITUTION: This composition is prepared by mixing an acrylic-functional silicone prepolymer having a plurality of acrylic groups bonded to Si atoms and represented by the formula (wherein R is H or CH3; and R1 is a divalent functional olefinically unsaturated hydrocarbon group) (e.g. an acryloxypropenyl- terminated silicone obtained by capping a bis-hydroxy-terminated polydimethylsiloxane with acryloxypropenyldimethylchlorosilane) with a silicone prepolymer having a plurality of organothiol groups (e.g. mercaptopropyl- containing polydimethylsiloxane) and an effective amount of a thiolene curing catalyst (e.g. diethoxyacetophenone).;COPYRIGHT: (C)1991,JPO
