ACRYLIC BLOCK COPOLYMER LOW TEMPERATURE FLOW MODIFIERS IN LUBRICATING OILS

摘要

The present invention relates to acrylic block copolymers synthesized by a
nitroxide mediated controlled radical polymerization having at least one
acrylic
block formed exclusively from acrylic monomers radical. Their use as low

temperature flow modifiers in oil-based compositions is also described. 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.
