Title:
METHOD FOR PRODUCING (METH)ACRYLIC COPOLYMER AND RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2020007501
Kind Code:
A
Abstract:
To provide a production method of a (meth)acrylic copolymer causing no deterioration of transparency under a heating condition and excellent in mechanical strength.SOLUTION: The (meth)acrylic copolymer comprises (A) a polymer chain composed of (P1) a copolymer having (a1) a polymer block having a unit derived from a diene and/or an olefin and (a2) a polymer block having a unit derived from an aromatic vinyl monomer and (B) a polymer chain having a unit derived from a (meth)acrylic monomer and is produced by a method including a step of initiating a radical polymerization reaction in the coexistence of the copolymer (P1), a (meth)acrylic monomer and a radical polymerization initiator and a polymerization step of adding the radical polymerization initiator to a reaction liquid after the initiation of the radical polymerization reaction.SELECTED DRAWING: None
