Abstract
A bio-sourced cationic polymer is obtained by reaction of epihalohydrin that is least partially renewable and non-fossil, and at least one compound of formula (R1)2N(CH2CH2NH)n(CH2CH2N(R2)2)m that is at least partially renewable and non-fossil. R1 and R2 are, independently of one another, a hydrogen atom H or an alkyl chain including 1 to 8 carbon atoms, n=0 to 3, m=0 or 1. When n=m=0, then a hydrogen atom H is covalently bound to the nitrogen atom N of the N(R1)2 group.
