Polymer combinations useful in distillate hydrocarbon oils to improve cold flow properties

摘要

Oil soluble ethylene polymers or copolymers having a Mn less than about 4000 in combination with an oil soluble polyester material such as a homopolymer or copolymer comprising, at least 10% by weight C4 to C16 substantially straight-chain alkyl esters of acrylic or methacrylic acid, are useful in improving the cold flow properties of distillate hydrocarbon oils.
