ABSTRACT:
A polymer composition comprising a styrene/maleic anhydride copolymer, a halogen-containing rubber, a halogenated aromatic flame-retardant, a flame-retardant synergist and a smoke suppressant comprising a mixture of dawsonite, calcium oxide and a magnesium compound. Such polymers have reduced combustibility and evolve less smoke when burned.
