Title (EN) WATER SOLUBLE EPOXY ESTER COPOLYMERS FOR SANITARY CAN USE
(FR) COPOLYMERES ESTERS EPOXYDES SOLUBLES DANS L"EAU UTILISES POUR LES SEAUX HYGIENIQUES
Abstract:
(EN) Water soluble epoxy ester copolymers adapted for sanitary can use comprise an hydroxy functional epoxy ester of a polyepoxide having an average molecular weight of about 300 to about 1100 and a 1,2-epoxy equivalency of about 1, 4 to about 2.0, esterified with an at least approximately stoichiometric proportion, based on epoxide functionality, of monocarboxylic acid selected from benzoic acid, C1-C8 alkyl substituted benzoic acid, and C6-C10 alkanoic acid, the esterification reaction being continued to provide an acid number of less than 20, this hydroxy functional epoxy ester is polyesterified with from 1.5-8%, based on the weight of the epoxy ester, of a monoethylenically unsaturated dicarboxylic acid which resists homopolymerization to an acid number of less than 20, and the polyester so obtained is copolymerized with from 15% to 70% of monoethylenic monomers, based on the copolymer, these monoethylenic monomers including carboxyl functional monomer providing an acid number of from 20-100 in the copolymer. The copolymers are dispersed in water by salt formation with an amine and aminoplast or phenoplast resin is incorporated to provide curing reactivity.
(FR) Des copolymeres esters epoxydes solubles dans l"eau utilisables pour les seaux hygieniques comprennent un ester epoxyde a fonction hydroxy d"un polyepoxyde ayant un poids moleculaire moyen d"environ 300 a 1100 environ et une equivalence 1,2-epoxy d"environ 1,4 a 2,0, esterifie au moins avec une proportion stoechiometrique, a fonction epoxyde, d"un acide monocarboxylique choisi parmi des acides benzoiques, un acide benzoique avec un groupe alkyle C1-C8 substitue, et un acide alcanoique C6-C10, la reaction d"esterification se poursuivant pour obtenir une valeur d"acidite inferieure a 20; cet ester epoxyde a fonction hydroxy est polyesterifie avec 1,5-8%, calcule en fonction du poids de l"ester epoxyde, d"un acide dicarboxylique monoethylenique non-sature qui resiste a l"homopolymerisation avec une valeur d"acidite inferieure a 20; et le polyester ainsi obtenu est copolymerise avec 15%-70% de monomeres monoethyleniques, bases sur le copolymere, ces monomeres monoethyleniques comprenant un monomere a fonction carboxyle donnant une valeur d"acidite de 20-100 dans le copolymere. Les copolymeres sont disperses dans l"eau par formation des el avec une amine et on incorpore une resine aminoplastique ou phenoplastique pour lui donner la reactivite voulue.
