摘要

The invention concerns a mixture containing: (a) between 10 and 90 wt % of at least one imide comprising a copolymer based on an alpha-olefin and an ethylenically unsaturated dicarboxylic acid and a polyamine; and (b) between 10 and 90 wt % of at least one reaction product of a poly (C2-20) carboxylic acid, comprising at least one tertiary amino group, with secondary amines.
