| 摘要 |
The present invention relates to a premixed blend of cellulose reactive first and second adducts, which first adduct comprises a cellulose reactive polyvinylamine first adduct composition comprising a reaction product of a starting polyvinylamine with at least a dialdehyde, wherein the starting polyvinylamine is a polymer formed from N-vinylformamide or N- vinylacetamide which polymer is at least partially hydrolyzed to impart a degree of primary amino functionality, prior to the reaction with the dialdehyde, and the second adduct comprised the reaction product of a dialdehyde with a starting polyvinylamide, with the proviso that the first and second cellulose reactive adducts are different. |
