摘要
Novel filter aid compositions enabling the improvement of limiting filterability temperature and the simultaneous inhibition of settling of the n-paraffin crystals formed at low temperature, comprising a mixture: of a compound A chosen from among the group of polymers or copolymers having a molecular weight between 500 and 15000 and having a branching rate between 10 and 30 points per 100 carbon atoms; and a compound B resulting from the condensation of at least one cyclic anhydride and at least one linear N-alkyl-polyamine; the weight ratio between these constituents A and B being from 1:20 to 20:1.
