Document Type and Number:
WIPO Patent Application WO/1997/006202
Kind Code:
A1
Abstract:
A block polymer having functional groups at both ends of its molecule and comprising hydrophilic/hydrophobic segments. As the functional groups at both ends, the polymer carries amino, carboxy or mercapto at the 'alpha'-end and hydroxy, carboxy, aldehyde, vinyl, etc. at the 'omega'-end.
