They are prepared by reacting an acetylenic alcohol R1R2C(OH)C ­ CR3 with carbon dioxide under pressure and at elevated temperature in the presence of a copper salt and an amount of 0.02 to 10% by weight based on the acetylenic alcohol of an amine having a dissociation constant of more than 10-5 in water. The temperature may be from 30 to 200 DEG C. and the pressure from 3 to 100 atmospheres. A solvent may be used. The process may be operated batchwise or continuously. The products may be used as anti-icing agents or may be polymerized (see Group IV(a)). In Example 36, 2-methyl-2-hydroxybutane-3-one, 3-methyl-3-hydroxy-4-pentanone and 1-acetylcyclohexanol-(1) are obtained by alkaline hydrolysis of 5-methylene-4,4-dimethyl-1,3-dioxolane-2-one, 5 - methylene - 4 - methyl-4-ethyl-1,3-dioxolane-2-one and 5-methylene - 4,4-pentamethylene-1,3-dioxolane-2-one respectively.

    Abstract: A process for the production of copolymers comprises polymerizing at a temperature of 50 DEG to 150 DEG C. 1 to 50% by weight of a monomer of the general formula in which R and R1 are hydrogen or methyl and R11 is an alkyl radical containing 1 to 4 carbon atoms or an alkyl ether radical of formula -(CH2)2-O-(CH2)n-CH3 where n is 1 to 3, with 99 to 50% by weight of another ethylenically unsaturated polymerizable compound. The ether ester may be 1-acryloxy-1-ethoxyethane, 1-methacryloxy-1-ethoxyethane, 1-methacryloxy-1-butoxyethane, 1-acryloxy-1-isobutoxyethane, 1-methacryloxy-1-isobutoxyethane, 1-methacryloxy-1-[b -methoxyethoxy]-ethane, 1-acryloxy-1-[b -ethoxy-ethoxy]-ethane, 1-methacryloxy-1-methoxyethane, 1-crotonyloxy-1-ethoxyethane and 1-crotonyloxy-1-methoxy ethane. Many suitable comonomers are listed including the unsaturated carboxylic acids and their esters, amides, nitriles and anhydrides, unsaturated aldehydes and ketones, unsaturated alcohols and their esters and ethers, olefins and diolefins, vinyl aromatic hydrocarbons and halogenated derivatives thereof, vinyl and vinylidene chloride and vinyl heterocyclic compounds. Polymerization may be effected in the presence of solvents and diluents, e.g. alcohols, ketones, ethers, amides, aromatics and heterocyclics; catalysts, e.g. organic peroxides and hydroperoxides and azo compounds; and chain transfer agents, e.g. mercaptans. Examples describe the polymerization of 1-acryloxy-1-ethoxyethane with (1) butyl acrylate and styrene; (2) butyl acrylate and acrylamide; (3) vinyl propionate and (11) butyl acrylate; of (4) 1-methacryloxy-1-isobutoxyethane with vinyl propionate and methyl methacrylate; of (5) 1-methacryloxy-1-[b -methoxyethoxy]-ethane with methyl methacrylate and butyl acrylate; of (6) 1-crotonyloxy-1-methoxyethane with acrylic acid, ethyl acrylate and styrene; of (7) 1-methacryloxy-1-butoxyethane with t.-butyl acrylate and acrylonitrile; of (8) 1-acryloxy-1-[b -ethoxyethoxy]-ethane with N-butyl acrylamide, butyl acrylate and dimethyl itaconate; of (9) 1-methacryloxy-1-ethoxy ethane with N-butoxymethyl methacrylamide, dichlorostyrene and dibutyl fumarate; and of (10) 1-crotonyl-1-ethoxy ethane with butanediol monoacrylate, dibutyl maleate and styrene. The copolymers may be dissolved in organic solvents, e.g. dioxane, toluene, cyclohexanone, butanol and butyl acetate, optionally together with urea-formaldehyde condensates, butanol etherified urea-formaldehyde condensates, melamineformaldehyde condensates, phenol-formaldehyde condensates, polyamides, aliphatic or aromatic epoxy resins, non-cross-linked reaction products of a dicarboxylic acid and pyrrole, and optionally curing catalysts such as phosphoric acid, and used for the production of films, lacquers, varnishes, coatings for wood and metals, for impregnating, textile finishes and pigment printing pastes, and cross-linked by heating.
