Ester and Amide Functionalization of Maleated Polyolefins as Pour Point Depressants for Kumkol Waxy Crude Oil

Pour point depressants (PPDs) based on functionalized polyolefins were obtained and evaluated for their efficiency in pour point reducing of Kumkol waxy crude oil (Kazakhstan), which contains 15.2 wt.% paraffin and has a pour point of +17 °C. An ethylene–propylene copolymer (EPR-505A) was treated th...
