摘要：
A novel chelate polymer having the formula: ##STR1## wherein R is a 2-thiazolyl or 2-benzothiazolyl group, is produced by reacting polymaleimide, formaldehyde, and m-aminobenzoic acid in the presence of a solvent, then coupling the resultant reaction product with a diazotized compound of 2-aminothiazole or 2-aminobenzothiazole. The novel polymers thus produced are useful as metal indicators or pH indicators.
