Abstract
A quaternized polymer having recurring units of the formula ##STR1## wherein X.sup..crclbar. represents an anion derived from an organic or mineral acid; PA1 R'.sub.2 is an aliphatic radical having a maximum of 20 carbon atoms; PA1 R'.sub.1 is an aliphatic, alicyclic or arylaliphatic radical containing a minimum of 2 carbon atoms and a maximum of 20 carbon atoms, or R'.sub.1 and R'.sub.2 together with the nitrogen atom to which they are attached form a ring capable of containing a second heteroatom other than said nitrogen; PA1 A represents a divalent group of the formula ##STR2## wherein x, y and t are whole numbers ranging from 0 to 11 and being such that the sum (x+y+t) is greater than or equal to 0 and less than 18, and E and K represent hydrogen or an aliphatic radical having less than 18 carbon atoms; PA1 B represents a divalent group of the formula ##STR3## wherein D and G represent hydrogen or an aliphatic radical having less than 18 carbon atoms and v, z, and u are whole numbers ranging from 0 to 11, two of them being able to be simultaneously equal to 0 such that the sum (v+z+u) is greater than or equal to 1 and lower than 18, and such that the sum (v+z+u) is greater than…
