UN PROCEDIMIENTO PARA PREPARAR POLIMEROS O COPOLIMEROS QUE CONTIENEN AL MENOS 25% EN PESO DE GRUPOS N-ALQUILO.

摘要

Polymers or copolymers containing an n-alkyl ester of a mono-ethylenically unsaturated C4 to C8 mono- or dicarbocylic acid wherein the average number of carbon atoms in the n-alkyl groups is from 12 to 14, and which contain no more than 10 wt. % of comonomer containing alkyl groups containing more than 14 carbon atoms and preferably no more than 20 wt.% of comonomer in which the alkyl group contains fewer than 12 carbon atoms are low temperature flow improvers for distillate fuels improving flow and filterability as well as lowering cloud point.
