STYRENE MALEIC ANHYDRIDE COPOLYMER with CAS 9011-13-6

COA-9011-13-6-SMA5500what is of  STYRENE MALEIC ANHYDRIDE COPOLYMER with CAS 9011-13-6?

The simplest form of transparent styrene-maleic anhydride copolymer (S-MA) is prepared by reacting styrene monomer with a small amount of maleic anhydride monomer. Maleic anhydride monomer is randomly attached to PS main chain, which increases the glass transition and thermal deformation temperature. Generally, the thermal deformation temperature of styrene-maleic anhydride copolymer products exceeds 260 F. During injection molding, even when the temperature exceeds 550°F, the properties of this polymer are still quite stable.
