<p>Heterotelechelic oligomers or polymers represented by general formula (I), wherein A represents a definite saccharide residue; L represents (Ia) or (Ib) (wherein R1 and R2 represent each independently lower alkyl, aralkyl or aryl); X represents a single bond or -CH2CH2-; Z represents a functional group, for example, a group forming an unsaturated ester or ether, halogen bonded to -CH2CH2-, etc.; n is a number of from 5 to 10,000 and m is 0 or a number of from 2 to 10,000; and micelles with the use of a block polymer of a polyethylene oxide having a saccharide residue at one end with a polyester. These oligomers or polymers are expected to have a high bioavailability and be usable in the fields of drug carriers and diagnostics.</p> |
