ABSTRACT:
A polymeric compound, named poly(amino-s-triazine), which has a layer structure with a structural unit represented by (C.sub.3 N.sub.3).sub.2 N.sub.x H.sub.y, where 2.ltoreq.x.ltoreq.4 and 0.ltoreq.y.ltoreq.8, is obtained by reaction of cyanuric trichloride with ammonia or melamine. This compound is stable in the air up to about 400.degree. C. and exhibits fluorescence by excitation at wavelength of 365 nm. When the above reaction is carried out at a temperature ranging from room tempertaure to about 400.degree. C. the product is an oligomeric compound (C.sub.3 N.sub.3).sub.a (NH).sub.b (NH.sub.2).sub.c Cl.sub.d, where 2.ltoreq.a.ltoreq.10, 1.ltoreq.b.ltoreq.10, 0.ltoreq.c.ltoreq.11 and 1.ltoreq.d.ltoreq.12, and poly(amino-s-triazine) is obtained by heating the oligomeric compound at 400.degree.-600.degree. C. in an inactive gas. The oligomeric compound too exhibits fluorescence and is higher in fluorescence intensity. An alkali metal ion can be introduced into poly(amino-s-triazine) by treatment with an alkali metal hydroxide solution, or hydroxyl group can be introduced by treatment with a mineral acid. In either case the modified polymer is very higher in fluorescence intensity and narrower in the width of flurorescence peak.
