Patent

CA 2366474

Novel polymers are provided having phosphonated and sulphonated substituent groups such that the polymer is multifunctional in its use. Optional amide substituents are used to reduce electrostatic charge density or for hydrogen bonding. An advantage of the polymer is the flexibility of using it for multiple purposes. A particular application is for bonding paper fillers and paper fiber together.

L'invention concerne de nouveaux polymères qui renferment des substituants phosphonés et sulphonés, rendant le polymère multifonctionnel. D'éventuels substituants amides sont utilisés afin de réduire la densité de charge électrostatique ou afin d'assurer une liaison hydrogène. Un des avantages du polymère est sa flexibilité d'utilisation à des fins diverses. Le polymère peut, en particulier, être utilisé pour lier des agents de charge pour papier et de la fibre papier.
