    摘要: (Meth)acrylic copolymers of general formula ##STR1## in which: the M.sup.+ are monovalent cations arising from the neutralization of the --COOH groups, it being possible, however, for this neutralization to have been only partial;R.sub.1 and R.sub.2 are chosen from: hydrogen, long-chain linear or branched cycloalkyl or alkyl radicals and aryl radicals having from 8 to approximately 22 carbon atoms, with the condition that at least one of R.sub.1 and R.sub.2 is not hydrogen;R.sub.3 and R.sub.4 are independently chosen from: the hydrogen atom, short-chain cycloalkyl or alkyl radicalshaving from 1 to 7 carbon atoms and aryl radicals having from 6 to 7 carbon atoms;R.sub.5, R.sub.6, and R.sub.7 are each, independently of one another, chosen from the hydrogen atom and the methyl radical;.tau..sub.1 is the molar level of long-chain amide units in the copolymer; and.tau..sub.2 is the molar level of short-chain amide units optionally present in the copolymer.Their weight-average molar mass does not exceed 30,000 and .tau..sub.1 is between 0.01 and 0.30.

    摘要: A low tack, low VOC gel coat is disclosed comprising a unsaturated polyester resin derived from maleic anhydride and up to about 30% of an organic solvent. The resin is characterized by: a viscosity of less than or equal to about 1750 cp at 70% NVM in styrene; a glass transition temperature greater than or equal to about 11° C.; and a weight average molecular weight less than or equal to about 6,050. A process for making such a gel coat is also disclosed.

    摘要: Polyester resin-based molding compositions, and methods for making and using the same, are described which have an improved maturation profile upon addition of a thickening agent. The improved maturation profile results from the presence of at least one multivalent metal salt of a non-fatty acid or anhydride in the molding composition added in accordance with the invention.
