摘要
The present invention relates in part to poly(styrene-co-maleic anhydride/acid) copolymers having high purity, for example, having low amounts of maleic acid, maleic anhydride, and/or styrene. The present invention also relates in parts to methods of purifying poly(styrene-co-maleic anhydride/acid) copolymers to remove the residual monomers and low molecular weight fragments.
