A method for improving the compatibility of random (vinyl substituted aromatic / C4-C6 conjugated diolefin) copolymers-asphalt mixtures

摘要

The present invention relates to a method for improving the compatibility of random vinyl substituted aromatic / C4-C6 conjugated diolefin polymer / asphalt mixtures comprising adding a modifier to said random vinyl substituted aromatic / C4-C6 conjugated diolefin polymer / asphalt mixture selected from the group consisting of: (a) polymers containing an epoxy functionality (b) polymers containing a carboxyl functionality (c) monomers, oligomers, and polymers containing an amine functionality; (d) monomers, oligomers, and polymers containing an ester functionality; or mixtures thereof.
