Patent ID: 8202924

Claim:
An organic solvent-free process for the production of a water-insoluble halogen-free oligomer or polymer of a 1,3,5-triazine derivative according to the general formula (I): wherein X is selected from: or X is a heterocyclic radical containing in the ring at least one nitrogen atom which radical is linked to the triazine ring through one of such nitrogen atoms, R 2 is alkyl or cycloalkyl, R 1 is a divalent radical of piperazine of the formula or R 1 is a divalent radical of the formula n is an integer in the range of 8 to 20, m is an integer in the range of 2 to 6, p is an integer in the range of 2 to 12 and, X 1 ═OH, NH 2 or X, whereby X 1 and X may be same or different, the process including the steps of: a) condensing a cyanuric halogenide with an amine of formula R 2 —NH 2 or with a heterocyclic compound containing in the ring a nitrogen atom, in a molar ratio of about 1:1, to obtain the 4-amino derivative of 2,6-dichloro-1,3,5-triazine, subsequently b) reacting the 4-amino derivative of 2,6-dichloro-1,3,5-triazine with one or more compounds selected from: an amine of formula H 2 N—(CH 2 ) m —NH 2 , or with piperazine or with an alkyl-substituted derivative of piperazine, wherein the 4-amino derivative of 2,6-dichloro-1,3,5-triazine and the one or more said further compounds are present in a molar ratio of about 1:1 and subsequently, c) reacting the reaction product(s) of the foregoing step with a compound of the formula HX 1 in the presence of a base, which base is selected from one or more of an excess of HX 1 or at least one alkali metal hydroxide.
