PROCESS FOR PRODUCING SHAPED ARTICLES FROM UNSATURATED POLYESTER RESINS

A process for the production of moldings from unsaturated polyester resins wherein a mixture is first prepared from 1. an unsaturated polyester, 2. a copolymerizable vinyl compound, 3. an inhibitor, 4. a photoinitiator, 5. a thickener, preferably MgO, 6. a pulverulent auxiliary which transmits ultra...

Summary:A process for the production of moldings from unsaturated polyester resins wherein a mixture is first prepared from 1. an unsaturated polyester, 2. a copolymerizable vinyl compound, 3. an inhibitor, 4. a photoinitiator, 5. a thickener, preferably MgO, 6. a pulverulent auxiliary which transmits ultraviolet light and/or 7. a fibrous reinforcing material and 8. further conventional additives. This mixture is thickened, where appropriate after coating onto a sheet-like carrier, to form a semi-finished product, which is then finally shaped, and cured by UV irradiation after which it may or may not be heat-treated.
