poly(styrene-co-maleic anhydride)

polymer

Poly(styrene-co-maleic anhydride) is a random copolymer combining styrene and maleic anhydride units, offering both rigidity from the styrene backbone and reactive functionality from the anhydride groups. This combination makes it particularly valuable in adhesives, compatibilizers for polymer blends, and coatings where both mechanical performance and chemical reactivity are needed. The anhydride groups enable post-polymerization modifications and improved adhesion to polar substrates, distinguishing it from unfunctionalized polystyrene in applications requiring bonding or surface treatment.

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
