Abstract
1288639 Modified butadiene polymers DAI NIPPON TORYO KK 9 Dec 1969 [9 Dec 1968 10 Dec 1968 (2) 11 Dec 1968 4 Nov 1969] 60141/69 Heading C3P [Also in Division C7] The invention comprises water soluble modified butadiene polymers, suitable for use in electrophoretic coating compositions, which polymers are made by reacting with maleic anhydride, one or more butadiene polymers of Mn 500 to 7000 and containing 70% or more of 1,2- bonding, so that 5-20% by weight based on the butadiene polymer of the anhydride has reacted, and esterifying the resulting adduct with an esterification agent containing at least one primary or secondary alcoholic hydroxyl group, to an esterification degree of 10 to 50%. The esterification agent may be a glycol monoether, a monofunctional primary or secondary aliphatic, aromatic or heterocyclic alcohol, each having up to 18 carbon atoms, an asymmetric glycol having 3-10 carbon atoms, or an aliphatic monohydroxy carboxylic acid, having 18 or less carbon atoms, or an ester thereof. Many examples are listed. Specific embodiments for making the above modified butadiene polymers involve bubbling air or oxygen through the molten butadiene polymer, at 80-160‹ C., and then adducting with maleic anhydride and esterifying, or bubbling air through the polymer after the adduction and esterification, again at 80-160‹ C. Compositions are made by mixing 5-95% by weight of the modified butadiene polymer, preferably 50-95% by weight, with 95-5%, preferably 50-5% by weight of at least one water-soluble or dispersible resin, compatible with the butadiene polymer i.e. mixes homogeneously with it. Compatible resins mentioned are acrylic resins, alkyd resins, epoxy ester resins, phenolic resins, adducts of drying oils with α,#-ethylenically unsaturated dicarboxylic acids and their half esters, water soluble amino resins and derivatives thereof, and watersoluble derivatives of phenolic resins. In another particular embodiment the butadiene polymer, after adduction with maleic acid is mixed with 5-95 weight per cent preferably 10-70% by weight of the adduct of a drying oil with an α,#- ethylenically unsaturated dicarboxylic acid, and the mixture is half esterified at 70-130‹ C. with one of the above esterification agents to an esterification degree of 10-50%. The product may be mixed with a "compatible resin". In an example, maleinized linseed oil is used. The compositions are made into electrophoretic coating compositions by neutralization with ammonia or amines, and dissolution in water or water/water-miscible solvent, mixtures.
