1.2.1.5MethylVinylEther-MaleicAnhydrideCopolymer
The key characteristic of these polymers is that degradation occurs by surface erosion thereby offering precise control of dissolution kinetics and drug release.18 In an aqueous environment the carboxylic acid groups on the polymer become ionized making the polymer water soluble but erosion only occurs at the surface. The degradation is highly pH dependent with increased degradation at higher pH.
