Abstract: THERMOSETTING MOLDING COMPOSITIONS ARE PREPARED USING POLYMERIZALE UNSATURATED POLYESTERS, POLYMERIZABLE UNSATURATED MONOMERS AND POLYMERS DERIVED FROM THE POLYMERIZATION OF A MIXTURE OF VINYL CHLORIDE AND VINYL ACETATE. FILLERS AND REINFORCING AGENTS ARE INCORPORATED IN THE COMPOSITIONS TO OBTAIN THE DESIRED PHYSICAL AND CHEMICAL PROPERTIES IN END USE APPLICATIONS. THESE COMPOSITIONS PRODUCE MOLDED ARTICLES HAVING LOW SHRINKAGE, DIMENSIONAL STABILITY AND IMPROVED SURFACE SMOOTHESS CHARACTERISTICS.

Abstract: A COLORED THERMOPLASTIC RESIN IS APPLIED IN FILM FORM OR AS POWDER ONTO THE SURFACE OF AN UNCURED FORMULATED LOW PROFILE POLYESTER SHEET AND IS THEN BONDED THERETO WITH HEAT, FORMING A LAMINATE OF THE CURED POLYESTER WITH CONTINUOUS, ADHERENT OVERLAYERS OF THE COLORED THERMOPLASTIC RESIN. A METHOD FOR COLORING POLYESTER SURFACES AFTER MOLDING WITH PIGMENTED THERMOPLASTIC RESIN POWDER IS ALSO DESCRIBED.

Abstract: UNSATURATED POLYESTER COMPOSITIONS PARTICULARLY FOR USE IN THE PREPARATION OF BULK MOLDING COMPOUND AND SHEET MOLDING COMPOUND STOCKS WHICH ARE CHEMICALLY THICKENED PRIOR TO CURING, BY INCORPORATION THEREIN OF FROM 0.5 PART TO 10 PARTS, PER 100 PARTS OF THE RESIN STSTEM, OR AN OXIDE OR HYDROXIDE OF A GROUP II-A METAL, E.G., CA(OH)2 AND MGO, ADDITIONALLY CONTAIN A MINOR QUANTITY OF A WATER-ABSORPTIVE, BUT ESSENTIALLY WATER-ISOLUBLE COMPOUND WHICH IS, E.G., A SYNTHETIC ZEOLITE, SILICA GEL OR CALCIUM SULFATE. ANY OF THESE MATERIALS SERVE TO SCAVENGE SUFFICIENT WATER IN THE FORMULATION TO KEEP ITS INTIAL VISCOSITY INCREASE TO A MINUMUM AND PROVIDE AN EXTENDED WORK-LIFE THERETO. THE AGING VISCOSITY BUILD-UP IN THE FORMULATION SURPRISINGLY THEN SPROCEEDS AT A SIGNIFICANTLY ACCELARATED RATE SO THAT THICKENING OF THE POLYESTER TO A DESIRED HIGH LEVEL CAN

BE ATTAINED TYPICALLY WITHIN 24 HOURS AFTER ITS PREPARATION.

Abstract: 1302167 Water-soluble polyelectrolyte polymers DIAMOND SHAMROCK CORP 13 Nov 1970 [14 Nov 1969] 54197/70 Heading C3P [Also in Division C1] Water-soluble polyelectrolyte polymers suitable for use as flocculants comprise the reaction product of (A) an acrylonitrile or methacrylonitrile polymer or copolymer, (B) water and (C) a primary or secondary amine or a polyamine having at least one primary or secondary amine group, components (B) and (C) being reacted in proportions of 0À2-15 moles and 0À8-20 moles, respectively, per mole of polymerized (meth)- acrylonitrile units in (A). Components (A) to (C) are suitably reacted at temperatures of 80-250‹ C. Preferred amines (C) include mono- or dimethylamine, mono- or di-ethanolamine, monoisopropanolamine, ethylenediamine, diethylenetriamine, N,N - dimethyl - 1,3 - propanediamine, 3 - methoxypropylamine, 1-(2- aminoethylamino) - 2 - propanol, N - (2 - aminoethyl) - ethanolamine, N - (3 - aminopropyl)- morpholine and N-(3-aminopropyl)-diethanolamine. Comonomers for the polymer (A) include olefins, halogenated olefins (e.g. vinyl chloride) acrylic acids and esters and amides thereof, styrene compounds, vinyl esters and vinyl ethers.
