Abstract
The present invention relates to acrylic block copolymers synthesized by a controlled free-radical process, and their use as low temperature flow modifiers in oil-based compositions. They are especially useful in modifying the low temperature flow behavior in lubricating oils. The acrylic copolymers are especially useful as pour point depressants in lubricating oil.
