Abstract
Thermoplastic compositions include from about 20 wt % to about 80 wt % of a polyphenylene ether (PPE), from about 1 wt % to about 30 wt % of a polystyrene resin that does not include a rubber component, and from about 0.01 wt % to about 10 wt % of a chemically reactive impact modifier. The combined weight percent value of all components does not exceed 100 wt %, and all weight percent values are based on the total weight of the composition. The compositions are resistant to bubbling upon processing.
Claims15
A thermoplastic composition comprising:
- a. from about 20 wt % to about 80 wt % of a polyphenylene ether (PPE);
- b. from about 1 wt % to about 30 wt % of a polystyrene resin that does not comprise a rubber component;
- and
- c. from about 0.01 wt % to about 10 wt % of a chemically reactive impact modifier,
- wherein the combined weight percent value of all components does not exceed 100 wt % and all weight percent values are based on the total weight of the composition, and
- wherein the composition is resistant to bubbling.
