Abstract
A composition comprises poly(arylene ether), a rubber modified poly(alkenyle aromatic) resin, and an unsaturated impact modifier. The composition may further comprise an encapsulated fluoropolymer. The melt strength of the composition, measured as the hang time of an extruded tube, is especially suited for blow molding methods. The composition exhibits good melt strength, surface quality and/or sandability and is particularly useful in blow molding applications.
Claims28
A blow molding composition comprising:
- about 20 wt % to about 80 wt % of a poly(arylene ether) resin;
- about 80 wt % to about 20 wt % of a high impact polystyrene;
- and
- about 2 wt % to about 15 wt % of an unsaturated impact modifier;
- wherein all weight percentages are based on the total weight of the composition and prior to blending the poly(arylene ether), the high impact polystyrene and the unsaturated impact modifier, the high impact polystyrene has particle sizes of about 2 micrometers to about 20 micrometers.
