    摘要: This invention provides a heterotelechelic oligomer or polymer which is represented by formula below:


    wherein R 1 and R 2 form an acetal, or, combined with each other, denote oxy (= O),

    p, m, n and q each denote a certain integer,
    L is a group which forms an ester, and
    Z denotes a certain functional group.


    This invention also provides a process to produce the above oligomer or polymer by means of living polymeri-zation. Since this oligomer or polymer forms a high- molecular micelle which is stable in an aqueous solvent, said oligomer or polymer will be useful as a carrier for drug delivery.
