ABSTRACT:
Additives for improving the low temperature flow properties and oxidative stability of hydrocarbon oils are disclosed, which comprise the alkylation of a phenol in the presence of a dipolar aprotic cosolvent to produce an essentially linear alkylated phenol which is condensated with a sulphurizing agent to produce the low temperature flow improver wherein:
