A note on the two SMA types which are named. Dylark is no longer available as Nova chemicals seized production in July 2009, Cadon does no longer exist since the sale of Solutia to Hercules. Today there are therefore only two major commercial producers of SMA, Sartomer with exclusively low Moleculaire weight products typically below 20.000, and Polyscope who provides SMA copolymers with a Moleculaire weight between 5000 and 180.000, and a Maleic anhydride content between 8 and 42%, including post-impact modified grades (Comparable to former Dylark resins).
