Abstract
A composition comprises a bitumen and a poly(arylene ether) having an intrinsic viscosity less than 0.40 deciliters per gram. The composition exhibits high softening and flow temperatures, and high hardness.
Claims29
A composition, comprising:
- about 0.1 weight percent to about 20 weight percent poly(arylene ether) having an intrinsic viscosity less than 0.4 deciliters/gram at 25° C. in chloroform;
- and
- bitumen.
A composition comprising:
- about 1 to about 3 weight percent of a poly(arylene ether) having an intrinsic viscosity less than 0.4 deciliters/gram at 25° C. in chloroform;
- about 5 to about 15 weight percent of a block copolymer of an alkenyl aromatic compound and a conjugated diene;
- and
- about 50 to about 94 weight percent bitumen;
- wherein all weight percents are based on the total weight of the composition.

A composition comprising:
- about 1 to about 3 weight percent of a poly(arylene ether) comprising poly(2,6-dimethyl-1,4-phenylene ether) having an intrinsic viscosity less than about 0.2 deciliters/gram at 25° C. in chloroform;
- about 5 to about 15 weight percent of a block copolymer of an alkenyl aromatic compound and a conjugated diene comprising block-poly(styrene-butadiene-styrene), block-poly(styrene-(ethylene-butylene)-styrene), or a mixture comprising at least one of the foregoing block copolymers;
- and
- about 50 to about 94 weight percent bitumen;
- wherein all weight percents are based on the total weight of the composition.
2 more elements
A method of preparing a composition, comprising:
- blending a bitumen and a poly(arylene ether) having an intrinsic viscosity less than 0.4 deciliters/gram at 25° C. in chloroform to form a mixture wherein the poly(arylene ether) is in the form of a powder having an average particle not greater than about 200 micrometers.
A method of preparing a poly(arylene ether)-containing composition, comprising:
- blending a poly(arylene ether) and a block copolymer of an alkenyl aromatic compound and a conjugated diene to form a first mixture;
- and
- blending the first mixture and bitumen to form a second mixture wherein the poly(arylene ether) is in the form of a powder having an average particle size not greater than about 200 micrometers.
