摘要： This invention relates to unsaturated polyester resins having reduced smoke levels and/or flame spread. The invention comprises incorporating particulate organic carboxylic acid into a polyester resin. Preferably the resin is a fire-retardant formulation and the presently-preferred carboxylic acid employed in particulate form is fumaric acid.

摘要： A SOLID WATER EXTENDED POLYESTER RESIN IS FORMED BY ESTERIFYING A POLYCARBOXYLIC ACID WITH A POLYOL, AND ADDING A CROSSLINKING AGENT, FORMING A WATER IN OIL EMULSION STABILIZED BY AN EMULSIFYING AGENT, AND THEREAFTER POLYMERIZING THE RESIN. THE EMULSIFYING AGENT IS SELECTED FROM BENZYLDIMETHYLAMINE, TRIMETHYLHEXAMETHYLENEDIAMINE, ISOPHORONEDIAMINE AND MORPHOLINE.

摘要： PAINT ADHENSION TO CURED POLYESTER-BASED RESINS IS SEVERELY DETERIORATED BY THE ADDITION OF LOW-SHRINK ADDITIVES TO THE UNCURED RESIN. THIS INVENTION IS A METHOD OF IMPROVING PAINT ADHENSION TO LOW-SHRINK FORMULATED POLYESTER-BASED RESINS BY THE ADDTION OF CERTAIN NITROGEN-CONTAINING VINYL MONOMERS TO THE UNCURED RESIN.

摘要： WATER EXTENDED THERMOSETTABLE RESIN COMPOSITIONS ARE PREPARED BY FORMING STABLE WATER-IN-RESIN EMULSIONS WITH VINYL ESTER RESINS, CERTAIN MODIFIED VINYL ESTER RESINS AND VINYL ESTER/UNSATURATED POLYESTER RESIN COMPOSITIONS. THE RESIN PHASE CONTAINS FROM 30 TO 60 PERCENT BY WEIGHT OF AN ESSENTIALLY WATER INSOLUBLE MONOMER COPOLYMERIZABLE WITH SAID RESINS. THE EMULSIONS ARE PREPARED TO CONTAIN FROM 30 TO 70 PERCENT BY WEIGHT WATER. THE NOVEL WATERIN-RESIN EMULSIONS ARE PREPARED WITHOUT THE NEED FOR AN EMULSIFYING AGENT. THE VINYL ESTER RESINS EMPLOYED ARE COMPOUNDS CONTAINING A PLURALITY OF TERMINAL UNSATURATED ACID ESTER GROUPS OBTAINED BY REACTION OF COMPOUNDS HAVING A PLURALITY OF OXIRANE GROUPS WITH ALPHA, BETA-UNSATURATED CARBOXYLIC ACIDS.

摘要： The viscosity of unsaturated polyester resins formed by mixing the condensation polymers of unsaturated dicarboxylic acids and dihydric alcohols in ethylenically unsaturated copolymerizable monomers may be greatly increased by adding (1) a mixture of calcium oxide and either calcium hydroxide or magnesium oxide, and (2) an organic acid selected from the group consisting of benzoic acid, cyclohexane carboxylic acid, cinnamic acid and phydroxybenzoic acid to the unsaturated polyester resins. The viscosity of the composition is initially low enough so that fibrous reinforcements can be impregnated with the resin composition and the low viscosity permits the resin to wet the fibers, thereafter the viscosity of the resin increases and the fibrous reinforced mass loses its tackiness and can be easily stored and handled.

摘要： POLYESTER RESINS OF INCREASED FLEXIBILITY AND STRENGTH ARE OBTAINED BY MIXING USUALLY LIQUID, UNSATURATED POLYESTERS WITH CERTAIN, USUALLY LIQUID, POLYMERIZABLE POLYDIENE ETHYLENICALLY-UNSATURATED ESTERS HAVING TERMINAL, ALLYLIC, ACYLOXY GROUPS, SUCH AS ACRYLYLOXY, WHICH ARE TERMINALLY ETHYLENICALLY-UNSATURATED, THEREBY FORMING USUALLY LIQUID POLYMERIZABLE COMPOSITIONS WHICH ARE POLYMERIZABLE TO SOLID POLYMERS. COMMERCIAL UNSATURATED POLYESTER RESINS CONTAINING 0 TO ABOUT 75% BY WEIGHT OF STYRENE CAN BE USED. FROM ABOUT 5 TO 95% OF THE POLYMERIZABLE POLYDIENE ETHYLENICALLY-UNSATURATED ESTER CAN BE USED IN THE COMPOSITION, ALTHOUGH USUALLY ABOUT 10 TO 50% BY WEIGHT IS PREFERRED.
