    Abstract: Compositions useful as pour point depressants, novel compounds within such compositions, and processes for making same, as well as lubricant oil compositions containing same, are disclosed. The novel compounds are encompassed by the general structural formula (I) Ar(R)-[Ar'(R')]n-Ar'' (I) wherein the Ar, Ar' and Ar'' are independently an aromatic moiety containing 1 to 3 aromatic rings and each aromatic moiety is substituted with 0 to 3 substituents, (R) and (R') are independently an alkylene group containing about 1 to 100 carbon atoms with the proviso that at least one of (R) or (R') is CH2, and n is 0 to about 1000; with the proviso that if n is 0, then (R) is CH2 and each aromatic moiety is independently substituted with 0 to 3 substituents with one aromatic moiety having at least one substituent, the substituents being selected from the group consisting of a substituent derived from an olefin and a substituent derived from a chlorinated hydrocarbon. The composition of the invention includes compounds varying in molecular weight from about 271 to about 300,000.

    Abstract: An asphalt cement mixture is disclosed. The mixture has improved antistripping properties due to the inclusion therein of a minor amount of an antistripping agent produced by the condensation reaction of an amine, an aldehyde or aldehyde reaction synthon an alkylated phenol. The antistripping agent is preferably present in the asphalt cement in an amount of from about 0.25% to about 1% by weight based on the weight of the asphalt cement. The asphalt cement is combined with an aggregate to form a concrete and paved onto a road surface to provide a paved surface with improved durability.
