摘要:
Methods of preparing a cross-linked, polymer-modified asphalt is provided. The method involves adding a crosslinking agent to asphalt prior to the addition of a crosslinkable polymer and an acid. Asphalt prepared by the disclosed methods exhibit improved properties such as properties measured by the Multiple Stress Creep Recovery (MSCR) test.
摘要:
The present invention is directed to an “warm” asphalt paving composition that contains an modified asphalt binder and aggregate, wherein the asphalt binder is modified, at least in part, by the addition of a hydrated phosphate modifier to the asphalt.

The present invention is directed to an air-blown roofing asphalt modified with polyphosphoric acid and roofing products made with the polyphosphoric acid-modified, air-blown asphalt.
摘要:
Anionic, especially sulfoaroyl, NaO.sub.3 S(C.sub.6 H.sub.4)C(O)- preferred, end-capped esters useful as soil release agents in detergent compositions and fabric-conditioner articles. The terephthalate esters contain unsymmetrically substituted oxy-1,2-alkyleneoxy units (oxy-1,2-propyleneoxy units preferred).
