Abstract
Borated derivatives of C.sub.8 to C.sub.40 hydrocarbyl substituted Mannich bases such as those derived from the condensation reaction of a C.sub.8 -C.sub.40 alkyl substituted hydroxy aromatic compound (said alkyl preferably having a linear chain of 16 to 22 carbons), an aldehyde and a mono (C.sub.2 -C.sub.3 alkanol) amine, preferably wherein the molar ratios of said aromatic to said aldehyde to said amine is about 1 to 0.9-1.4 to 0.9-1.4, respectively, are useful in combination with a coadditive hydrocarbon such as an amorphous hydrocarbon or a hydrogenated polybutadiene in improving the cold flow properties of distillate hydrocarbon oils.
