Title:

PROCESS FOR THE PREPARATION OF AMPHIPHILIC POLY (N-VINYL-2-PYRROLIDONE) BLOCK COPOLYMERS

Document Type and Number:

WIPO Patent Application WO2005054319

Kind Code:

A9

Abstract:

The instant invention provides a two-step polymerization process for preparing amphiphilic poly(N-vinyl-2 pyrrolidone), (PVP)-block-polyester copolymers and other diblock and triblock copolymers consisting of PVP as one block. The block copolymers of the invention can be used as vehicles for drug delivery.
