Patent ID: 8709168

Claim:
A method of improving soil resistance of a hard surface, comprising: applying to the hard surface a composition comprising a polymer of Formula (I): R 1 [A 1 {(PO) n (EO) m H} 2 ] p [A 1 (PO) n (EO) m H] q [A 1 ] r (I) wherein R 1 represents the molecular framework of a quaternized polyamine apart from p+q+r quaternized groups; A 1 independently represents a tertiary N atom; a quaternary group N + R 2 An s- 1/s wherein R 2 represents a C 1 to C 6 alkyl or a C 7 to C 10 aralkyl group and An represents a charge balancing anion carrying a charge of s-; or a quaternary nitrogen betaine group; PO represents propyleneoxy; EO represents ethyleneoxy; n represents a value from 10 to 100; m represents a value from 5 to 100; p represents the number of alkoxylated/quaternized primary amino groups in the polymer; q represents the number of alkoxylated/quaternized secondary amino groups in the polymer; r represents the number of quaternized tertiary amino groups in the polymer; and p+q+r represents a value in the range 200 to 1200.
