| titleOfInvention | Method for producing rubber-modified α, β-unsaturated carbonyl polymer resin composition |
| abstract | (57) [Problem] To provide a rubber-modified α, β-unsaturated carbonyl polymer resin composition capable of controlling the molecular weight even with a small amount of a chain transfer agent. SOLUTION: A mixed solution comprising an α, β-unsaturated carbonyl monomer represented by the following formula (1) and, if necessary, another monomer copolymerizable with these monomers and a solvent is used. A solution prepared by a polymerization method using an alkali metal compound or an alkaline earth metal compound as an initiator, and a solution in which a rubber-like polymer having an unsaturated double bond in a molecule is dissolved, In a radical polymerization method using a compound containing active hydrogen as a chain transfer agent, the rubbery polymer is previously treated with an acidic compound in an amount equal to or more than the equivalent of the alkali metal compound or alkaline earth metal compound used in the polymerization. A method for producing a rubber-modified α, β-unsaturated carbonyl polymer resin composition. [R1] [R2] C = C [R3] H Formula (1) (where R1 is an alkoxycarbonyl group, an alkylcarbonyl group, a cyano group. R2 and R3 are each a hydrogen, a hydrocarbon residue or an oxygen. , Sulfur and nitrogen-containing hydrocarbon residues.) |
