POUR POINT DEPRESSANTS FOR BIODIESELS

摘要

A cold flow improver for biodiesels is provided to improve a CFPP(Cold Filter Plugging Point) and a pour point of fuel oil containing the biodiesels and to improve breathability of a fuel filter remarkably. A cold flow improver for biodiesels contains terpolymers. The terpolymers are acquired from a mixture including a compound of a chemical formula 1, a compound B and a compound C having comonomer. The chemical formula 1 is CH2=CR^1-COOR^2. The R^1 is a hydrogen atom or methyl radical. The R^2 is an alkyl group of C1~C30.
