| abstract |
The present invention provides a polymer-modified bitumeniferous composition containing polymer components in the amount of 0.5-50 wt. %, wherein 20-100 wt. % of the polymeric additive is a copolymer comprises of units of: C 6 -C 28 -alkyl (meth)acrylates in the amount of 80-99.9 wt. %, maleic anhydride in the amount of 0.1-20 wt. %, and other polymerizable compounds in the amount of 0-19.9 wt %. The polymer-modified bitumens exhibit excellent and persistent homogeneity, high elastic resilience, and a good range of plasticity. |
