| abstract |
The present invention relates to a flame-retardant resin composition having halogen content of 2 to 40% by weight basing on the amount of said composition, which comprises (a) 100 parts by weight of a styrene-based polymer having mainly syndiotactic configuration, or a mixture of 99 to 50% by weight of said styrene-based polymer and 1 to 50% by weight of a thermoplastic resin (exclusive of tetrafluoroethylene-based polymer) and/or rubber; (b) 3 to 40 parts by weight of a flame retardant selected from the group consisting of halogenated polystyrenes and halogenated polyphenylene oxides and (c) 1 to 15 parts by weight of an auxiliary flame retardant, as main components. In addition, the present invention contains the above components (a), (b) and (c) as main components, and further contains (d) 0.003 to 10 parts by weight of tetrafluoroethylene-based polymer and/or (e) 1 to 300 parts by weight of an inorganic filler. The present invention provides a resin composition which is excellent in flame retardance and further in heat resistance. |
