UNGESÄTTIGTE POLYESTERHARZZUSAMMENSETZUNGEN UND NEUES ANTISCHRUMPFMITTEL

摘要

Liquid resin compositions appropriate for moulding objects reinforced by glass fibres and which may be pigmented, comprising an unsaturated polyester, a copolymerizable monomer and a partially hydroxylated alkyl methacrylate polymer. The polymer selected is a hydroxylated alkyl methacrylate polymer which is soluble in the monomer and miscible with the unsaturated polyester. Application to the fabrication of moulded objects by mass moulding, sheet moulding and by injection.
