    Abstract: A METHOD IS PROVIDED FOR INCREASING THE RATE OF CURING OF A LIQUID COATING AND MOLDING COMPOSITION TO FORM AN INFUSIBLE RESINOUS ARTICLE OR COATING. THE COMPOSITION COMPRISES A SOLUTION OF A POLYMERIZABLE OLEFINICALLY UNSATURATED MONOOXIRANE COMPOUND SUCH AS GLYCIDYL METHACRYLATE, A SOLID POLYANHYDRIDE HAVING AT LEAST THREE SUCCINIC ANHYDRIDE GROUPS (EXCLUDING AROMATIC ANHYDRIDES IN WHICH THE ALPHA CARBON ATOMS OF THE ANHYDRIDE GROUP ARE INCLUDED IN THE AROMATIC RING), FOR EXAMPLE, THE COPOLYMER OF A STRAIGHT CHAIN ALPHA-MONOOLEFIN AND A MALEIC ANHYDRIDE; AND CERTAIN OLEFINICALLY UNSATURATED MONOMERS FREE OF OXIRANE OXYGEN ATOMS, SUCH AS STYRENE OR ACRYLONITRILE. THE RATE OF CURING OF THIS COMPOSITION CAN BE INCREASED BY ADDING TO THE ABOVE DESCRIBED COMPOSITION A SMALL AMOUNT OF WATER ON THE ORDER OF 0.5 WEIGHT PERCENT. THE WATER IS EFFECTIVE FOR INCREASING THE RATE OF CURING FOR THE ABOVE COMPOSITION WHETHER THE COMPOSITION IS CURED THERMALLY, WITH THE USE OF A FREE RADICAL CATALYST SUCH AS AN ORGANIC PEROXIDE, FOR EXAMPLE BENZOYL PEROXIDE, WITH A SOLUBLE TERTIARY AMINE SUCH AS 3-PICOLINE, OR WITH A COMBINATION OF HEAT, ORGANIC PEROXIDES AND TERTIARY AMINES.

    Abstract: LIQUID COATING AND MODING COMPOSITIONS ARE PROVIDED WHICH ARE CURABLE TO AN INFUSIBLE RESIN ARTICLE OR COATING. THE COMPOSITION COMPRISES A SOLUTION OF A SATURATED OR UNSATURATED MONOOXIRANE COMPOUND, FOR EXAMPLE EPICHLOROHYDRIN, A MONOANHYDRIDE OF A DICARBOXYLIC ACID CONTAINING AT LEAST 5 CARBON ATOMS, SUCH AS PHTHALIC ANHYDRIDE AND A SOLID POLYANHYDRIDE HAVING SUCCINIC ANHYDRIDE GROUPS (EXCLUDING AROMATIC ANHYDRIDES IN WHICH THE A -CARBON ATOMS OF THE ANHYDRIDE GROUP ARE INCLUDED IN THE AROMATIC RING) FOR EXAMPLE THE COPOLYMER OF A STRAIGHT CHAIN A -MONOOLEFIN AND A MALEIC ANHYDRIDE. PREFERABLY A TERTIARY AMINE, SUCH AS 3-PICOLINE, IS INCLUDED AS A CURE ACCELERATOR. THE COMPOSITION SHOWS LITTLE OR NO SHRINKAGE AND WEIGHT LOSS DURING DURING, IN CONTRAST TO THE SAME COMPOSITION MINUS THE MONO-ANHYDRIDE. THUS FOR EXAMPLE, FILMS AND COATINGS FREE OF LIFTING AND ETCHING ARE OBTAINED.

    Abstract: MALEIC ANHYDRIDE AND AN ALIPHATIC OLEFIN HAVING FROM 20 TO 30 CARBON ATOMS, SUCH AS A MIXTURE OF ALPHA-OLEFINS HAVING FROM 20 TO 30 CARBON ATOMS, ARE COPOLYMERIZED IN THE PRESENCE OF A FREE-RADICAL CATALYST AND A SOLVENT SUCH AS A SATURATED DIHALOGENATED ALIPHATIC LIQUID HYDROCARBON HAVING FROM ONE TO FIVE CARBON ATOMS, FOR EXAMPLE PROPYLENE DICHLORIDE. ENOUGH SOLVENT IS EMPLOYED TO SOLUBILIZE NOT ONLY THE REACTANTS BUT ALSO THE COPOLYMER PRODUCTS. THE COPOLYMER IS PRECIPITATED IN A FILTERABLE PARTICULATE SOLID FORM SUBSTANTIALLY FREE OF MONOMERS BY COOLING THE ENTIRE REACTION PRODUCT TO A TEMPERATURE FROM ABOUT 35*C. TO ABOUT 55*C. AND ADMIXING THE COOLED REACTION PRODUCT WITH AN ALIPHATIC MONOHYDROXY ALCOHOL HAVING THREE CARBON ATOMS PER MOLECULE, SUCH AS N-PROPANOL, WHILE MAINTIANING THE DESIRED COOL TEMPERATURE.

    Abstract: MALEIC ANHYDRIDE AND AN ALIPHATIC OLEFIN HAVING AT LEAST 30 CARBON ATOMS PER MOLECULE ARE COPOLYMERIZED IN THE PRESENCE OF A SOLVENT COMPRISING AN ALIPHATIC KETONE HAVING FROM 3 TO 5 CARBON ATOMS, SUCH AS METHYLETHYLKETONE, AND IN THE PRESENCE OF A FREE-RADICAL CATALYST USING A SUFFICIENT AMOUNT OF KETONE TO MAINTAIN NOT ONLY THE REACTANTS BUT ALSO THE COPOLYMER PRODUCTS IN SOLUTION. THE UNREACTED MONOMERS ARE PRECIPITATED FROM THE REACTION PRODUCT SOLUTION IN A FILTERABLE PARTICULATE SOLID FORM BY COOLING THE REACTION PRODUCT SOLUTION TO A TEMPERATURE LESS THAN THE CRYSTALLIZATION TEMPERATURE OF THE ALIPHATIC OLEFIN IN THE PRESENCE OF SUFFICIENT ADDITIONAL AMOUNTS OF KETONE SOLVENT, IF REQUIRED, TO MAINTAIN THE COPOLYMER IN SOLUTION AND PRECIPITATE THE OLEFIN MONOMER IN A FINELY DIVIDED FILTERABLE FORM. THE PRECIPITATED MONOMER CAN THEN BE SEPARATED FROM THE COPOLYMER SOLUTION BY ANY SUITABLE MEANS, SUCH AS FILTRATION.
