ABSTRACT:
A process for producing a novel formamide group-containing copolymer, or a salt thereof, which can be used as a high-molecular weight amino reagent, a starting material for functional high-molecular weight compounds, a starting material for adhesives, a polymer compatibilizer, a resin modifier, etc., and can undergo hydrolysis to give a copolymer containing a primary amino group, and a novel copolymer containing a primary amino group obtained by hydrolysis, which comprises reacting a compound having a recurring unit derived from styrene, olefins or derivatives thereof, a recurring unit derived from dienes such as butadiene, and a recurring unit derived from acid anhydrides such as maleic anhydride, with a salt of a specific primary diamine in the presence of a formyl group-containing compound such as formamide, to effect imidation and/or amidation, and then deacidifying the product with a base, or by imidation and/or amidation of the above-mentioned copolymer with a reaction product obtained by reacting a primary diamine with a formyl group-containing compound such as formamide.
