High molecular weight, essentially linear, thermoplastic amino-s-triazine resins having an inherent viscosity of at least about 0.55 dl./g. are disclosed, comprising recurring units of the formula: ##STR1## containing not less than 25 wt. % of triamino-s-triazine units of the formula: ##STR2## Such resins are suitable for molding or extrusion into films, fibers and filaments and for preparation of composite materials. Also disclosed is a process for the production of high molecular weight essentially linear, thermoplastic amino-s-triazine resins which comprises reacting, in contact with water, an inert, water-immiscible organic solvent for at least one of the reactants and a basic acid acceptor, substantially equimolar proportions of a triazine compound or a mixture of triazine compounds of the formula: ##STR3## with a diamine or a mixture of diamines of the formula: ##STR4## until a thermoplastic amino-s-triazine resin having an inherent viscosity of at least about 0.55 dl/g., is produced.

Essentially linear, thermoplastic poly (amino-s-triazines)s and process

Compounds of the formula ##STR1## and polymers thereof are useful as ultraviolet radiation stabilizers for polymers.
