| description | A dispersion stabilizer for crude oils which contains a vinyl-alcohol-based polymer, characterized in that the vinyl-alcohol-based polymer has a degree of saponification greater than 70 mol% but not greater than 82 mol% and has a total content of carboxyl groups and lactone rings of 0.02-1 mol% with respect to all the constituent units of the vinyl-alcohol-based polymer. Thus, a dispersion stabilizer for crude oils is provided with which it is possible to disperse or emulsify a high-viscosity crude oil to thereby lower the viscosity and to make the obtained crude-oil dispersion or emulsion present stably for a long time.
Cette invention concerne un stabilisant de dispersion pour huiles brutes, caractérisé en ce que le polymère à base d'alcool vinylique a un degré de saponification supérieur à 70 % en mol mais inférieur ou égal à 82 % en mol et a une teneur totale en groupes carboxyle et cycles lactone de 0,02 à 1 % en mol par rapport à tous les motifs constitutifs du polymère à base d'alcool vinylique. Le stabilisant de dispersion pour huiles brutes selon l'invention permet par conséquent de disperser ou d'émulsifier une huile brute à haute viscosité pour abaisser ainsi sa viscosité et stabiliser la dispersion ou l'émulsion d'huile brute obtenue pendant longtemps. |
