  • Patent number: 4014955
    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.

  • Patent number: 4001156
    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.

  • Patent number: 3985825
    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.
