The invention relates to compositions comprising an organoclay and polyphenylene ether resin and blends containing polyphenylene ether resin. In a preferred embodiment, the compositions exhibit physical properties that are enhanced over compositions containing clay of the prior art. The invention also relates to methods to enhance the ductility of thermoplastic compositions as compared to compositions containing clay of the prior art. The invention also relates to articles made from the compositions.

Compositions with enhanced ductility

A method for determining flame retardance of polymer compositions includes subjecting a plurality of specimens of a polymer composition to a flame test and performing a statistical analysis of the data obtained. The statistical analysis includes determining the probability of at least one possible outcome of the flame test. The probability of possible outcomes provides a measure of the flame retardance of the polymer composition. A preferred flame test is the UL-94 flame test.
