Separation of statistic MMA-MAA Copolymers using Gradient SEC
contributed by PSS |
Introduction
Statistic copolymers of methyl methacrylate (MMA) and methacrylic acid (MAA) are used in pharmaceutical applications. The molar mass distribution, the chemical composition and the amount of comonomers are of importance. Characterization by gradient HPLC failed due to pronounced breakthrough peaks.
SEC-gradients has been successfully applied to measure the amount of MAA.
