| Abstract |
The present invention discloses a novel pH sensitive copolymer synthesized from lactide macromers and basic monomers. This composition comprises an acrylate or methacrylate ester of low molecular weight oligomeric lactide copolymerized with basic monomer. These copolymers show pH sensitive dissolution behavior which can be exploited for pharmaceutical applications. |
