FIELD: polymer materials.
SUBSTANCE: invention relates to incombustible, weakly foaming polybutylene terephthalate-based polymer composition, which can be used injection casting and extruding construction- and decorative construction-destination parts for motor cars, aircrafts, and other vehicles as well as in electrical engineering. Composition contains 79.5-91% polybutylene terephthalate, 4-10% decabromodiphenyl oxide or its mixture with antimony trioxide, 1-3% polytetrafluoroethylene, and additionally 4-15% modifier, in particular polyblock-structure block copolymer obtained by interaction of butanediol with oligotetramethylene oxide.
EFFECT: increased fire-resistant characteristics.
