摘要:
Disclosed herein is a flame retardant composition comprising a polycarbonate; a polylactide; and a flame retardant; where the flame retardant is a phenoxyphosphazene, a di- or polyfunctional aromatic phosphorus-containing compound, or a combination comprising at least one of the foregoing flame retardants. Disclosed herein is a method comprising blending a polycarbonate, a polylactide and a flame retardant to form a flame retardant composition; where the flame retardant is a phenoxyphosphazene, a di- or polyfunctional aromatic phosphorus-containing compound, or a combination comprising at least one of the foregoing flame retardants.
摘要:
Disclosed herein is a flame retardant composition comprising 20 to 80 weight percent of a polycarbonate composition; where the polycarbonate composition comprises a polysiloxane-carbonate copolymer; an impact modifier in an amount of 0.5 to 25 weight percent; and 1 to 20 weight percent of a phosphazene compound; where all weight percents are based on the total weight of the flame retardant composition. Disclosed herein too is a method comprising blending 20 to 80 weight percent of a polycarbonate composition; where the polycarbonate composition comprises a polysiloxane-carbonate copolymer; an impact modifier in an amount of 0.5 to 25 weight percent; and 1 to 20 weight percent of a phosphazene compound to produce a flame retardant composition; where all weight percents are based on the total weight of the flame retardant composition; and extruding and molding the flame retardant composition.
摘要:
An impact resistant polycarbonate composition having improved resistance to polymer degradation comprises an aromatic polycarbonate in admixture with an elastomer-modified graft copolymer that is the product of an emulsion polymerization process, wherein composition is a product of compounding the aromatic polycarbonate and the elastomer-modified graft copolymer in the presence of a buffer comprising a potassium salt of phosphoric acid.
摘要:
The present disclosure relates to a thermoplastic composition having a better mold release performance. The disclosed thermoplastic composition comprises polycarbonate components, an impact modifier and a mold release composition. Also disclosed is a method for making the disclosed thermoplastic composition and an article of manufacture comprising the disclosed polymer composition.
摘要:
This disclosure relates to thermoplastic compositions, in particular polycarbonate thermoplastic compositions containing a surface-treated talc, methods for the manufacture of such compositions, and articles formed from the compositions.
摘要:
A polycarbonate composition comprises an elastomer-modified graft copolymer prepared by an emulsion polymerization process in which an elastomer phase is polymerized or copolymerized in the presence of an electrolyte to obtain latex particles that is then grafted with a monomer mixture comprising a monovinylaromatic monomer.
