Abstract
Official abstract text for this publication.
A thermoplastic composition includes a poly(carbonate-arylate ester); and an organophosphorus compound in an amount effective to provide 0.1 to 1.0 wt % phosphorus based on the total weight of the composition, wherein an article molded from the composition has a smoke density after four minutes (Ds-4) of less than or equal to 300 determined according to ISO 5659-2 on a 3 mm thick plaque and a maximum average rate of heat release emission (MAHRE) of less than or equal to 90 kW/m 2 determined according to ISO 5660-1 on a 3 mm thick plaque.
First claim
Opening claim text (preview).
What is claimed is: 1. A thermoplastic composition comprising, based on the total weight of the composition, 88 to 98 wt % of a poly(carbonate-arylate ester), wherein the poly(carbonate-arylate ester) is a poly(carbonate-monoaryl arylate ester), a poly(carbonate-monoaryl arylate ester) comprising siloxane units, or a combination comprising at least one of the foregoing; and 2 to 12 wt % of bisphenol A bis(diphenyl phosphate); optionally, up to 5 wt % of an additive selected fr…
