There is disclosed a thermoplastic resin composition comprising as principal components a [A] thermoplastic resin having a functional group reactive with an amino group, a [B] olefinic polymer and/or styrenic polymer, the subtotal of the above [A]+[B] being 100 parts by weight, and 0.05 to 20 parts by weight of a [C] copolymer having a unit represented by ##STR1## wherein Y is a group selected from the groups of the general formula ##STR2##

Thermoplastic resin composition

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.

Formamide group-containing copolymer, process for producing the same,

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.

Process for producing formamide group-containing copolymer, and
