Abstract:
1. A polyurethane comprising: (a1) at least one cationic or cationizable unit derived from at least one tertiary or quaternary amine comprising at least two reactive functions containing labile hydrogen, wherein the amines forming the units (a1) are chosen from compounds of formulae: wherein: each R each R each R′b is chosen from H and a linear or branched C m and p are, independently of each other, equal to 0 or 1; each X is, independently, an oxygen or sulfur atom, or a group NH or NR A (a2) at least one nonionic unit derived from at least one polyolefin comprising at least two reactive functions containing labile hydrogen said polyolefin comprising at least 10 mol % of units comprising at least one C═C double bond, relative to the total amount of units forming said polyolefin; wherein the at least one polyolefin has hydroxyl end groups and is chosen from: at least one olefin homopolymer chosen from 1,2-butadiene, 1,4-butadiene and isoprene homopolymers in their cis and trans forms; 1,2-polybutadienes, poly(cis-1,4-isoprenes) and poly(trans-1,4-isoprenes); or at least one statistical olefin copolymer corresponding to the following structure: wherein: m, p and q are mole fractions ranging from 0 to 1, and m+p+q=1; n is an integer ranging from 10 to 100; x is 0 or 1, and X is a divalent carbon-based radical comprising 1 to 10 carbon atoms; and (b) at least one unit derived from a compound comprising at least two isocyanate functions.
