Abstract: Linear copolymers of glycidol, glycidyl esters of unsaturated fatty acids and, optionally, alkylene oxides, are made by the reaction of an unsaturated fatty acid with a polymer or copolymer of tert.-butyl glycidyl ether in the presence of an acid catalyst. The products are polymerizable and copolymerizable with vinyl monomers and are useful as curable resins.

Abstract: The cross-linked macromolecular polyethers containing ionic bonds are obtained by reacting polyhydric phenols which contain amino groups (Mannich bases) on the one hand with compounds which contain on average more than one epoxide group per molecule, and on the other hand with organic compounds which contain at least 2 halogen atoms. The reaction is on the one hand a polyaddition, and on the other a polyquaternization. The adducts manufactured in this way have a reduced tendency to take on a static charge and can be used with advantage in the textile and paper sectors.

Abstract: Resins containing epoxy groups and quaternary ammonium groups can be prepared by reacting an epoxy group-containing material and an amine acid salt. Boron is added to the composition either by adding a member selected from the group consisting of aqueous boric acid solution, boric acid, and compounds hydrolyzable to form boric acid in aqueous medium to the reaction product or by utilizing a material selected from the group consisting of amine salts of boric acid and amino-containing esters of boric acid as the amine salt constituent. It has now been found that when the reaction between the amine acid salt and the epoxy is conducted in the presence of a controlled amount of water, more uniform and desirable products can be obtained.

Abstract: The cross-linked macromolecular polyethers containing ionic bonds are obtained by reacting polyhydric phenols which contain amino groups (Mannich bases) with compounds which contain simultaneously epoxide groups and halogen atoms. An addition and a quaternization reaction occur. Optionally, it is possible to add simple organic halides to the reaction mixture. The adducts manufactured in this way have a reduced tendency to acquire a static charge and can be used with advantage in the textile and paper sectors.

Abstract: Adducts containing epoxide groups, which have been (so-called) "advanced" with polyesters containing rings are obtained by reacting adducts containing epoxide groups, which have been obtained by reaction of certain long-chain aliphatic polyesters with diepoxide compounds in excess, with polyesterdicarboxylic acids, containing carbocyclic or heterocyclic rings, while heating, 0.3 - 0.5 carboxyl group equivalent of the polyester-dicarboxylic acid containing rings being employed per 1 epoxide equivalent of the adduct containing epoxide groups. Curing of the (so-called) "advanced" adducts containing epoxide groups gives flexible moulded materials which are distinguished, in particular, by high tear propagation resistance.

Abstract: A water reducible epoxy ester is prepared by reacting an epoxy resin, preferably a diglycidyl ether of bisphenol A, and a monofunctional epoxy, such as phenyl glycidyl ether, with a dibasic acid (e.g., azelaic acid) followed by reaction with trimellitic anhydride and neutralization of free carboxyl groups. This material is dispersed in an aqueous vehicle, applied to a metal substrate and baked.

Abstract: Glass fiber-reinforced epoxy resins are rendered fire-protecting by incorporating in their moulding compositions a combination of three materials: a source of carbon, such as e.g. pentaerythritol, a source of phosphoric acid, such as e.g. a water-insoluble nitrogen-containing polymer phosphate, and a source of non-inflammable gases such as e.g. melamine.

Abstract: Objects which are designed to be submersed or submerged are rendered antiling by using an organotin polymer wherein the tin is chemically combined in or bonded to the polymer. The polymer inhibits fouling of the exposed surface of the object while minimizing the effect on the surrounding environment due to reduced leaching of the organometallic compound from the polymer.

The resins are derived from epoxy group containing organic materials and are essentially epoxy group free. When dispersed or dissolved in water, the boron-containing, quaternary ammonium salt-containing resins can be applied to a wide variety of different substrates by electrodeposition, and will deposit on the cathode to provide coatings of unique properties.
