Abstract

The present invention discloses poly(styrene-co-maleic anhydride/acid) and methods for their preparation using solventless techniques. In addition to the absence of potentially toxic solvents, the methods results in reduced amounts of residues, such as unreacted styrene and/or maleic anhydride monomers, which makes the copolymers suitable for bioapplications.
