CA 2475579

The invention relates to products, especially moulding materials of polymers containing triazine segments and consisting of mixtures of meltable 4-18 ring oligotriazine ethers which are soluble in highly polar solvents, and in which the triazine rings are predominantly linked by alkylene diamino groups. Said moulding materials can contain up to 50 mass % of other reactive polymers such as ethylene copolymers, maleic acid anhydride copolymers, modified maleic acid anhydride copolymers, poly(meth)acrylates, polyamides, polyester and/or polyurethanes, up to 75 mass % of filling materials and/or reinforcing fibres, and up to 2 mass % of stabilisers, UV absorbers and/or auxiliary agents. The moulding materials of polymers containing triazine segments can be processed by means of conventional fusion methods and can be used as hot-melt adhesives and for producing plates, tubes, profiles, injection moulded parts, fibres, coatings and foamed material.

L'invention concerne des produits, en particulier des matières à mouler, à savoir des polymères contenant des segments triazine, constituées de mélange comprenant des éthers d'oligotriazine de 4 à 18 noyaux fusibles et solubles dans des solvants fortement polaires, dans lesquels les cycles triaziniques sont rattachés principalement par des groupes alkylènediamino. Ces matières moulables peuvent contenir jusqu'à 50 % en masse d'autres polymères réactifs du type copolymère d'éthylène, copolymère d'anhydride d'acide maléique, copolymère d'anhydride d'acide maléique modifié, poly(meth)acrylate, polyamide, polyester et/ou polyuréthanne, jusqu'à 75 % en masse de charges et/ou de fibres de renforcement, et jusqu'à 2 % en masse de stabilisateurs, d'absorbeurs UV et/ou de matières auxiliaires. Ces matières moulables, à savoir des polymères contenant des segments triazine, peuvent être traitées selon le procédé habituel de fusion et peuvent être utilisées comme colle fusible et pour la production de panneaux, de tubes, de profilés, de pièces moulées par injection, de fibres, de revêtements et de mousses.
