Fumarate copolymers and acylated alkanolamines as low temperature flow improvers |
| 摘要 |
The low temperature flow properties of wax-containing liquids are improved by adding a composition comprising (i) a polymer of a C8-20 alkyl ester of an ethyleneically unsaturated 1,2-diacid, and (ii) the reaction product of an alkanolamine with a C8-50 hydrocarbyl-substituted acylating agent.
