TL;DR: In this paper, a high-quality polycarbonate composition was proposed, which is free from a reduction in molecular weight by filtration, discoloration or the formation of foreign matter and obtained by using a polymer filter having a small opening size.
Abstract: To provide a high-quality polycarbonate composition comprising a polycarbonate which is free from a reduction in molecular weight by filtration, discoloration or the formation of foreign matter and obtained by using a polymer filter having a small opening size to have a low content of foreign matter. This composition comprises (A) a polycarbonate having a viscosity average molecular weight of 10,000 or more obtained by filtration in a molten state with a filter comprising an assembly of a plurality of disk filter elements having an outer diameter of 15 inches (38.1 cm) or less, an inner diameter/outer diameter ratio of 1/7 or more and an opening size of 40 μm or less, an inorganic filler (B1) and/or a thermoplastic resin (B2) other than polycarbonates.

04 Oct 2000TL;DR: In this paper, a flame retardant polycarbonate composition is defined, which includes polycarbonates and a silsesquioxane flame-resilient additive additive additive component, and an article can be molded from the composition.
Abstract: A flame retardant polycarbonate composition includes (A) at least one polycarbonate and (B) a silsesquioxane flame retardant. The flame retardant polycarbonate composition can be made by providing a polycarbonate and incorporating a flame retardant amount of a silsesquioxane into the polycarbonate. An article can be molded from the composition.
