Abstract
A dynamically vulcanized thermoplastic composition is provided which comprises a polymer blend of a polyolefin resin, a halogenated elastomeric copolymer, such as a halogenated butyl rubber, or a halogenated copolymer of a C.sub.4 to C.sub.7 isomonoolefin and a para-alkylstyrene, and a halogenated polyethylene. The composition has improved flame retarding properties. Additional flame retarding additives may be incorporated in the composition. The dynamically vulcanized thermoplastic composition is suitable for use in roofing sheets.
