Method for improving the compatibility of random vinyl substituted aromatic/C4-C6 conjugated diolefin polymer/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.
