A photosensitive resin composition which is excellent in flexibility and impact resilience, which is less affected by humidity is provided. This composition comprises a soluble synthetic polymer, a photopolymerizable unsaturated compound, and a photo-polymerization initiator, wherein the soluble synthetic polymer comprises an addition polymer obtained by the reaction between a diamine compound having amino groups selected from primary and secondary amino groups and having no amide bonds in its molecule and a diisocyanate compound; and the addition polymer contains a polyoxyalkylene glycol component in an amount of 20 to 80% by weight.
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 in a molecule thereof a formamide group and/or an amino group or a salt thereof, said copolymer having the repeating unit I, II, III or IV represented by the general formula (I), (II), (III) or (IV), respectively,
wherein Y is a group selected from the general formula
-NH-R¹³ (VII)
and other symbols are as defined in the specification. The above composition is excellent in impact characteristics, especially surface impact characteristics and appearance, minimized in coloration and free from delamination and peeling.

There are disclosed a copolymer having a secondary amino group such as an alkylpiperazino group or having a formamide group which is introduced via imide group in the side chains of various high polymers and a process for producing the above copolymer by reacting a starting copolymer having the repeating unit originating from an acid anhydride (e.g. maleic anhydride) with a salt of a specific amine (e.g. piperazine derivative) in the presence or absence of a formyl group-containing compound (e.g. formamide) to imidize the starting copolymer and further removing the acid with a base, or by imidizing the starting copolymer with the reaction product between the specific amine and the formyl group-containing compound. The above copolymer is usable for high molecular amino reagents, raw materials for functional high polymers, raw materials for additives, compatibilizers for polymers, resin dyeing improvers, epoxy resin curing agent, resin modifiers, etc.
