摘要： An adhesive composition comprises essentially (a) 100 parts by weight of a block copolymer of the formula A-B-A, wherein each A is an independently selected polymer block of a monovinylsubstituted aromatic hydrocarbon having a molecular weight between 8000 and 45,000, and B is a polymer block of a conjugated diene having a molecular weight between 35,000 and 150,000 or hydrogenated derivatives thereof, and (b) 50 to 150 parts of a fully hydrogenated ester of rosin, or a mixture of 10 to 150 parts by weight of a rosin-based resin together with 25 to 100 parts by weight of a coumarone-indene resin (which may be phenol modified), a polymerized hydrocarbon resin or a coal tar resin. Optional components comprise (c) 0 to 50 parts of a particulate filler, (d) 0 to 50 parts of a rubber extender oil, (e) 0 to 800 parts of a volatile liquid carrier, (f) natural or synthetic rubbers, (g) 10-100 parts of polystyrene, and (h) antioxidants or antiozonants, e.g. zinc dibutyl dithiocarbamate. For use as pressure-sensitive adhesive compositions, the compositions preferably utilize a fully hydrogenated ester of rosin, while for use as contact or heat-activated adhesive compositions, it is preferred that a resin mixture of class (b) is also incorporated. Suitable rosin-based resins include wood, polymerized, hydrogenated, disproportionated, dimerized, pentaerythritol esters of, pentaerythriol esters of hydrogenated or polymerized, glycerol esters of, glycerol esters of hydrogenated, or methyl esters of hydrogenated rosins. Exemplified components are (a) polystyrene-polybutadiene-polystyrene and polystyrene - polyisoprene, polystyrene, (b) a pentaerythritol ester of hydrogenated rosin, a polymerized wood rosin, and partially and completely hydrogenated pentaerythritol esters of rosin, coumarone-indene resins, and (c) hexane-toluene-acetone mixture and (d) polystyrene.

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： A NOVEL MODIFIED POLYPHENYLENE OXIDE WHICH IS STABLE AGAINST THERMAL OXIDATION IS PREPARED BY CONTACTING A VINYL ETHER COMPOUND WITH A LEWIS ACID IN THE PRESENCE OF A POLYPHENYLENE OXIDE TO POLYMERIZE THE VINYL ETHER COMPOUND. SAID REACTION MAY BE EFFECTED IN THE PRESENCE OR ABSENCE OF A REACTION MEDIUM, SUCH AS ALIPHATIC OR ALICYCLIC HYDROCARBONS OR AROMATIC HYDROCARBONS OR DERIVATIVES THEREOF. THE REACTION TEMPERATURE IS USUALLY BELOW 140*C. THE AMOUNT OF THE LEWIS ACID IS PREFERABLY 0.0001 TO 10% BY WEIGHT BASED ON THE TOTAL AMOUNT OF THE REACTION MIXTURE.

摘要： 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.
