A thermoplastic composition, comprising: about 10 to about 84 wt. % of a polycarbonate resin; about 0.5 to about 40 wt. % of a polycarbonate-polysiloxane copolymer; 1 to about 40 wt. % of an impact modifier composition; and about 1 to about 50 wt. % of an alkyl (meth)acrylate polymer; each based on the total combined weight of the thermoplastic composition, exclusive of any filler. In another embodiment, the thermoplastic composition may comprise about 10 to about 85 wt. % of a polycarbonate resin; about 1 to about 40 wt. % of an impact modifier composition; and about 1 to about 50 wt. % of an impact-modified alkyl (meth)acrylate polymer; each based on the total combined weight of the thermoplastic composition, exclusive of any filler. The compositions have improved weld line strength, and are useful in the manufacture of molded parts, especially for electronic devices.

Polycarbonate compositions, articles, and method of manufacture

A method for increasing the crystallization rate of a polyethylene terepthalate (PET) prepared based on terepthalic acid (TPA) and ethylene glycol monomers, by adding into said TPA-based PET an effective amount of a polyethylene terepthalate prepared based on dimethyl terephthalate (DMT), in an amount sufficient for said thermally formable composition to have an increase in crystallization temperature as required for the final end-use application.

Polyethylene terephthalate compositions

A polyester composition includes a poly(butylene terephthalate), a nitrogen-containing flame retardant, and a phosphorus-containing flame retardant, such that the weight ratio of the total of the nitrogen-containing flame retardant and the phosphorus-containing flame retardant to poly(butylene terephthalate resin) is at least about 0.70, and the weight ratio of the phosphorus-containing flame retardant to the nitrogen-containing flame retardant is at least about 1.0. The compositions have excellent color stability under ultraviolet light aging, good flame retardance, and high impact strength.

Flame-retardant polyester composition, method for the preparation thereof, and articles derived therefrom

The present invention provides resin compositions comprising a thermoplastic resin, at least one phosphoramide having a glass transition point of at least about 0&deg; C. preferably of at least about 10&deg; C., and most preferably of at least about 20&deg; C.; and at least one adjunct flame retardant. The present invention also relates to articles made from the resin compositions. The present invention also provides methods to make the resin compositions having improved heat properties over compositions known in the art.

Flame retardant resin compositions containing phosphoramides, and method of making

The present invention provides resin compositions comprising a thermoplastic resin and at least one phosphoramide having a glass transition point of at least about 0&deg; C., preferably of at least about 10&deg; C., and most preferably of at least about 20&deg; C. The present invention also relates to articles made from the resin compositions. The present invention also provides methods to make the resin compositions-having improved heat properties over compositions known in the art.
