Title:

ヘテロテレケリックブロックコポリマーおよびその製造方法

Document Type and Number:

Japanese Patent JP3855279

Kind Code:

B2

Abstract:

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.
