Patent

CA 2408737

The invention relates to a concentrated, non-agglomerating, soluble and compatible drag reducing agent composition. It contains (a) from 1 to 60% of a polymer, e.g. non-crystalline and ultrahigh molecular weight poly-.alpha.- olefin, capable of reducing drag, and (b) from 40 to 99% of a natural fat or oil, e.g. linseed or rapeseed oil, based on the combined weight of (a) and (b). Preferably, it also contains (c) from 0.1 to 50% of a dispersion stabilising agent, e.g. a fatty acid soap, based on the combined weight of (a), (b) and (c).

La présente invention concerne une composition d'agent réduisant la résistance au frottement qui soit concentrée, non agglomérante, soluble et compatible. Cette composition contient (a) de 1 à 60% d'un polymère et notamment une poly-.alpha.-oléfine non cristalline de masse moléculaire ultra-haute, capable de réduire la résistance au frottement, et (b) de 40 à 99% d'une graisse ou huile naturelle telle que l'huile de lin ou l'huile de colza, sur la base de la masse combinée de (a) et (b). La composition contient également de préférence (c) de 0,1 à 50% d'un stabilisant de dispersion tel qu'un savon d'acide gras, sur la base de la masse combinée de (a), (b) et (c).
