    Abstract: Thermosetting unsatd. polyester moulding compsns. contain a mixt. of an ethylenically unsatd. polyester (IA) or vinyl ester (IB) with terminal unsatd., ethylenically unsatd. monomers (II), which can copolymerise with (I), 5-200 (wt.)% fibrous reinforcement, 50-350% powdered filler, 0.1-4% organic free radical initiators and 0.1-6% viscosity reducing agent (III), all w.r.t. (I)+(II), and opt. the usual thickeners, shrinkage-reducing or elastifying organic polymers, lubricants, inhibitors, pigments and cure accelerators. The novelty is that (III) is an amino-acid of formula: (R1)(R2)N-X-COOH (III) R1 = H or 1-4C alkyl; R2 = 6-30C satd. or unsatd., linear or branched aliphatic alkyl or acyl; X = 1-6C linear or branched alkylene.

    Abstract: Crystallite suspensions containing from 3 to 70 weight percent of a crystalline, ethylenically unsaturated polyester prepared through condensation polymerization, and having a molecular weight factor per double bond of 154.4 to 408, as the dispersed phase, and from 30 to 97 weight percent of a polyhydroxyl compound having a functionality of from 2 to about 8, a hydroxyl number of from 20 to 800, and a melting point of less than 30 DEG C. as the coherent phase are suitable for preparing non-cellular and cellular polyurethane- or polyurethane group-containing polyisocyanurate foams.

    Abstract: 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.
