Abstract
A method for the manufacture of a reactive polymer, which comprises causing (A) a polymer containing a free carboxylic group in an acid equivalent in the range of 0.01 to 5 milliequivalent/g and (B) an unsaturated aziridine compound possessing one aziridinyl group and at least one radically polymerizable unsaturated group in the molecular unit thereof to react with each other in proportions such that the amount of said unsaturated aziridine compound falls in the range of 0.05 to 1.2 mole per 1.0 mole of said free carboxylic group of said polymer at a temperature in the range of 40.degree. to 150.degree. C., and the reactive polymer obtained by such method.
