Process for producing thermoplastic resin composition

A process for producing a succinimide resin composition comprising reacting a maleic anhydride-olefin type copolymer constituted of 40-60 mol % of maleic anhydride units, 60-40 mol % of olefin units, and 0-20 mol % of a copolymerizable monomer units with one or more amine compounds for imide formation in the presence of a second polymer other than the succinimide resin, said second polymer being compatible with the succinimide resin, to form a succinimide resin having the units represented by General Formulas (1) and (2):

• 3
• where R1, R2, and R3 denote independently hydrogen, an alkyl of 1-6 carbons, or a cycloalkyl.

A process for producing a succinimide resin composition comprising reacting a maleic anhydride-olefin type copolymer constituted of 40-60 mol % of maleic anhydride units, 60-40 mol % of olefin units, and 0-20 mol % of a copolymerizable monomer units with one or more amine compounds for imide formation in the presence of a styrene-acrylonitrile copolymer to form a succinimide resin having the units represented by General Formulas (1) and (2):

• 4
• where R1, R2, and R3 denote independently hydrogen, an alkyl of 1-6 carbons, or a cycloalkyl.
