Abstract
Liquid resinous compositions suitable for the moulding of objects reinforced with glass fibres and capable of being pigmented, comprising an unsaturated polyester, a copolymerisable monomer and a partially hydroxylated alkyl methacrylate polymer. A hydroxylated alkyl methacrylate polymer which is soluble in the monomer and miscible with the unsaturated polyester is chosen. Application to the manufacture of objects moulded by bulk, sheet and injection moulding.
