植物-または動物源の燃料油用の冷間流動性改善剤
Document Type and Number:
Japanese Patent JP4768956
Kind Code:
B2
Abstract:
Additives containing (A) a copolymer of ethylene and an acrylate or vinyl ester and (B) a comb polymer derived from 8-16C alkyl ester(s) of unsaturated dicarboxylic acids and 10-20C olefin(s), in which the sum of the average molar C-chain distributions in the alkyl side chains of the olefins and in the fatty alcohols of the ester groups is 23-27. Additives (I) containing (A) a copolymer of ethylene and 8-21 mol% acrylate or vinyl ester with a 1-18C alkyl group and (B) a comb polymer derived from 8-16C alkyl ester(s) of unsaturated dicarboxylic acid(s) and 10-20C olefin(s), in which the sum Q of the average molar C-chain distributions in (a) the alkyl side chains of the olefin and in (b) the fatty alcohols in the ester groups = 23-27, Q being given by the expression Q = approximately Siw1i.n1i + approximately Sjw2j.n2j, where w1 and w2 are the molar proportions of individual chain lengths in (a) and (b) respectively, n1 and n2 are the side chain lengths in (a) without the original olefinic carbons and in (b) respectively, and the variables i and j are the individual side-chain lengths in (a) and (b). An Independent claim is also included for a fuel oil composition containing a fuel oil of animal or vegetable origin and an additive (I).
