ABSTRACT:
The present invention discloses styrene-maleic anhydride copolymers preparations using solventless techniques. The solventless method resulted in reduced amounts of residues, such as unreacted styrene and/or maleic anhydride monomers, which makes the copolymers particularly suitable for bioapplications.
