Disclosed is a thermosetting resin composition which comprises (a) an unsaturated polyester, (b) a polymer having a (meth)acrylate group only at one or both terminals of its main chain, (c) a poly(meth)acrylate oligomer, (d) a styrene monomer, and (e) a methyl methacrylate monomer. Also, a method of molding the resin is disclosed, which comprises dividing the thermosetting resin composition into two parts, adding a curing agent to one of the two parts and a curing accelerator to another to form two partial compositions, introducing the two partial compositions into a mold, and allowing the two partial compositions to mix with each other and cure.

On divulgue une composition de résine thermodurcissable qui comprend (a) un polyester insaturé, (b) un polymère possédant un groupe (méth)acrylate situé uniquement à l'une ou aux deux extrémités de sa chaîne principale, (c) un oligomère de poly(méth)acrylate, (d) un monomère de styrène, et (e) un monomère de méthyl-méthacrylate. Une méthode de moulage de la résine est également divulguée, qui comprend la subdivision de la composition de résine thermodurcissable en deux parties, l'addition d'un agent de durcissement à l'une des deux parties et d'un accélérateur de durcissement à l'autre pour former deux compositions partielles, l'introduction des deux compositions partielles dans un moule, ainsi que le mélange et le durcissement de deux compositions partielles.
