Title:
両末端に官能基を有するブロックポリマー
Document Type and Number:
Japanese Patent JP3711288
Kind Code:
B2
Abstract:
The present invention provides a block polymer which has functional groups on its both ends, and which comprises hydrophilic/hydrophobic segments. As for the functional groups on its both ends, the block polymer has amino group, carboxyl group or mercapto group on alpha -terminal, and hydroxyl group, carboxyl group, aldehyde group or vinyl group on omega -terminal. Hydrophilic segment comprises polyethylene oxide, while hydrophobic segment is derived from lactide, lactone or (meth)acrylic acid ester. The block polymer of this invention forms a polymeric micelle which is usable as bio-compatible materials.
