Beschreibung
Zusammenfassung:	A graft polymer comprises a carbohydrate polymer having pendant 3-amino-2-hydroxy propyl groups grafted thereon and may be employed as a retention aid and strengthening additive in paper manufacture. When the carbohydrate polymer is a component of wood pulp the resulting chemically modified wood pulp may be employed in conjunction with unmodified wood pulp to incorporate therein the retention and strengthening characteristics. Ce polymère greffé comporte un polymère glucidique possédant des groupes 3-amino-2-hydroxy propyle pendants greffés et pouvant être utilisé comme agent adjuvant de retenue et produit d'addition de renforcement lors de la fabrication de papier. Lorsque ce polymère glucidique est un composant de pulpe de bois, la pulpe de bois modifiée chimiquement qui en résulte peut être employée avec de la pulpe de bois non modifiée afin de lui conférer des qualités de retenue et de renforcement.
