FLAME-RETARDANT AND SHOCK-IMPROVED POLYCARBONATE COMPOSITION

摘要

This invention relates to an impact resistant carbonate polymer composition comprising a mixture of one or more carbonate polymers, an impact modifying quantity of a rubbery polymer containing residual ethylenic unsaturation and a fluorine-containing polymer of the fibril-forming type. The fluorine-containing polymer of the fibril-forming type reduces the susceptibility of the carbonate polymer to burning or at least minimizes the effects of dripping of molten polymer when the polymer is exposed to fire.
