Patent ID: 8663612

Claim:
A conditioning polymer consisting of monomers i), ii) and iii) wherein monomer -i) is a cationic monomer defined by formula (I) in which: R 1 and R 2 are independently hydrogen or methyl, R 3 , R 4 and R 5 are independently linear or branched C 1 -C 30 alkyl radicals, X is NH, NR 6 or oxygen, R 6 is C 1 -C 6 alkyl, L is C n H 2n , n is an integer from 1 to 5, and A− is an anion derived from an organic or inorganic acid; monomer ii) is a monomer of formula (VI): R 12 and R 13 are independently hydrogen or C 1 -C 6 alkyl, R 14 is hydrogen, C 1 -C 6 alkyl or a COOM group, M is hydrogen, a monovalent or divalent metal ion, ammonium or an organic ammonium ion, R 9 and R 10 of the diallyl component iii) are hydrogen and monomer iii) is a diallyl amine monomer defined by formulae (II) or (III) in which, R 7 and R 8 are independently hydrogen or C 1 -C 4 alkyl, R 9 is hydrogen, branched or linear C 1 -C 30 alkyl, C 1 -C 30 alkoxy, hydroxy substituted C 1 -C 10 alkyl, C 7 -C 9 alkylphenyl, carboxyalkyl, alkoxyalkyl and carboxyamidalkyl, R 10 is hydrogen, C 1 -C 20 alkyl, C 5 -C 10 cycloalkyl or an unsubstituted benzyl radical, with the proviso that if R 10 is other than hydrogen, then R 9 is AO is a C 1 -C 12 alkylene oxide or mixtures of C 1 -C 12 alkylene oxides, m is an integer from 2 to 200, R 11 is hydrogen or methyl; and the polymer is optionally crosslinked with a crosslinking agent.
