Abstract
A method for producing a (meth)acrylate copolymer via anionic polymerization of a mixture of a di(meth)acrylate and an alkyl (meth)acrylate in the presence of an organolithium compound, a tertiary organoaluminum compound, and at least one Lewis base selected from ethers and tertiary polyamines. The (meth)acrylate copolymer produced has a (meth)acryloyl groups in a side chain.
Claims10
A method for producing a (meth)acrylate copolymer, comprising:
- anionic polymerization of a mixture of a di(meth)acrylate represented by formula (1) and an alkyl (meth)acrylate represented by formula (2) in the presence of an organolithium compound, a tertiary organoaluminum compound comprising a chemical structure represented by formula (3) in its molecule, and at least one Lewis base selected from the group consisting of ethers and tertiary polyamines
- wherein R1 denotes a hydrogen atom or a methyl group, R2 denotes a linear alkylene group having 1 to 5 carbon atoms, and R3 and R4 each independently denote a hydrocarbon group having 1 to 6 carbon atoms
- wherein R5 denotes a hydrogen atom or a methyl group, and R6 denotes an alkyl group having 1 to 6 carbon atoms
- Al—O—Ar (3)
- wherein Ar denotes an aromatic ring
- wherein said (meth)acrylate copolymer produced by said method has (meth)acryloyl groups in a side chain thereof.
