Abstract

Bitumens can be blended with interpolymers prepared from least one olefin and at least one vinyl or vinylidene aromatic monomer and, optionally, at least one diene. The interpolymers prepared from monomers containing a diene are new compositions of matter. When the interpolymers prepared from monomers containing a diene are blended with a bitumen, the blends are crosslinkable.
