Polysaccharide aldehydes prepared by oxidation method and used as resistance additives in papermaking |
| abstract |
<B> POLYSACARID ALDEHYES PREPARED BY THE OXIDATION METHOD AND USED AS RESISTANCE ADDITIVES IN PAPER MANUFACTURING <D> Polysaccharide aldehydes are prepared using selective oxidation, involving the use of aqueous oxidation mediated with a nitroxyl radical limited amount of oxidant and defined reaction conditions. These polysaccharide aldehyde derivatives have minimal carboxylic acid and maximum effective aldehyde levels, which makes them especially useful as wet, temporary wet and dry strength additives for paper. |
