  • Bituminous composition with improved ‘walk-on-ability’ and its use in roofing applications
    Patent number: 7247664
    Abstract: Disclosed is a bituminous composition that comprises a bituminous component (A), an elastomer component (B), preferably a block copolymer of a conjugated diene and a monovinylaromatic hydrocarbon, and an additive (C), wherein the additive is a compound of the general formula Ar—R—Ar??(I) wherein each “Ar” independently is a benzene ring or fused aromatic ring system of 6 to 20 carbon atoms, substituted by at least one hydroxyl group, and “R” is an optionally substituted divalent radical comprising 6 to 20 atoms in the backbone and at least one amide and/or ester group in the backbone. These compositions are disclosed to be particularly useful in the preparing and repair of roofing.
