<p>A polymerizable composition, which comprises (A) a (meth)acrylic monomer or a partially polymerized material therefrom having been adjusted so as for the whole polymer component after polymerization to have a glass transition temperature of 20°C or lower, (B) a thermally conducting inorganic filler, (C) a photo polymerization initiator and (D) a heat polymerization initiator; and a method for producing an (meth)acrylic thermally conductive sheet, which comprises applying the polymerizable composition on a support with a thickness of 0.5 mm to 10 mm, laminating a protective sheet on the applied layer, and then irradiating the resultant laminate with a light beam. The above polymerizable composition allows the formation of a (meth)acrylic polymer with a satisfactorily high yield by the irradiation with a light for a short time with no heating step, and, in the above method a semi-transparent paper can be used as the above support and protective sheet, which reduce the production cost for the thermally conductive sheet.</p> |
