This disclosure relates to methods of making novel dissolving wood pulps by processes comprising acid prehydrolysis, pulping, and a multi-stage bleaching process comprising oxidation with a catalyst and peroxide under acidic conditions, as well as to products made therefrom having a combination of medium-purity, low viscosity, and improved reactivity, filterability, and/or clogging that can be used as a substitute for traditional high-purity dissolving pulps in a wide variety of applications.

The present disclosure generally relates to open chain modified cellulosic pulps and methods for making and using the same. More specifically, the open chain modified cellulosic pulps described herein may be made by oxidation of a cellulosic pulp, followed by reduction of the oxidized groups, resulting in a modified pulp having an improved open chain configuration that may be more efficiently converted into cellulosic derivative products. This disclosure further relates to improved cellulosic derivative products made therefrom, for example, cellulose esters, cellulose ethers, and regenerated cellulose products.
