A OLIGOMERIC LACTIDE MACROMER BASED COPOLYMER AND A PROCESS FOR THE PREPARATION THEREOF

摘要

Present invention discloses a novel copolymer comprising an acrylate or methacrylate ester of low molecular weight oligomeric lactide copolymerized with basic monomer. These copolymers show unusual dissolution behavior in that they are soluble over a wide range of pH from 1.8 to 7.4. This unexpected solubility behavior can be exploited to develop pharmaceutical dosage forms.
