Styrene maleic anhydride - Wikipedia

Styrene maleic anhydride (SMA or SMAnh) is a synthetic polymer that is built-up of styrene and maleic anhydride monomers. The monomers can be almost perfectly alternating, making it an alternating copolymer [citation needed], but (random) copolymerisation with less than 50% maleic anhydride content is also possible.
