Flame-retardant compositions.

摘要

Flame-retardant polymer compositions comprising a linear alternating copolymer of carbon monoxide and at least one olefinically unsaturated compound, and at least a flame-retarding quantity of at least one organohalogen compound containing one or more polyhalogen substituted rings and of a compound selected from the group consisting of antimony oxides, metal borates and mixtures thereof, wherein the compositions comprise, in addition polytetrafluoroethylene in a sufficient amount to render the compositions non-dripping.
