Title:
疎水性親水性AB型ブロックコポリマーの製造方法
Document Type and Number:
Japanese Patent JP4212064
Kind Code:
B2
Abstract:
The invention relates to a process for the preparation of hydrophobic-hydrophilic AB block copolymers wherein block A consists of the monomer unit a, which is conjugated diene, and block B consists of the monomer unit b, which is epoxide, and the invention also relates to the AB block copolymer synthesized by the preparation process, as well as to micellar systems made from the AB block copolymer. According to the invention, the AB block copolymer is synthesized in two steps, whereby the first step is the preparation of block A in a nonpolar solvent and the second step is the preparation of block B in a polar solvent.
