ABSTRACT OF THE DISCLOSURE The present invention provides a process for preparing polymers which contain s-triazine rings said process comprising reacting at a temperature of from 50°C to 350°C a cyanamide of a secondary amine s-triazine of the formula (II) Image wherein B and D independently of each other are -O-, -S-, -NH-, -NR-, -X-Q-Ay- or nil, R is alkyl, aryl or heterocyclic, X and A independently of each other are nil, -O-, -S-, -NH- or -NR-, Q is an organic radical, e.g. arylene, alkylene and/or heterocyclic, y means 0, 1, 2, 3 or 4 a = 1, 2 or 3 b = 0, 1 or 2 c = 0, 1 or 2 a+b+c = 3 with an organic compound E which con- tains -XH and/or -AH wherein X and A are as defined previously, except that in said compound X and A are not both nil. The polymers of the present invention are novel and have high glass transition temperatures and melting points. These novel polymers are useful as moulding powders, laminating resins and adhesives.
