ABSTRACT:
Novel polyureas of the formula: ##STR1## wherein n is 9 to 18, m is 2 to 10, X and Y are each either ethyl, methyl or a hydrogen atom and R=aromatic, aliphatic or cycloaliphatic, are described herein. These polyureas are particularly useful as thickening agents for lubricating oils to make greases. The polyureas may be prepared by reacting the aminated products of propoxylated fatty alcohols with organic polyisocyanates. The reaction is a simple process requiring no heat. Very low levels of the resulting polyureas are required to thicken oils of lubricating viscosity into greases which have good high temperature stability.
