Abstract
 
 
The papers contained in this thesis are a record of research carried out in the course of rny employment with the British Cotton Industry Research Association, Shirley Institute, Didsbury, Manchester, and have been published in the Shirley Institute Memoirs end in the Journal of the Textile Institute.
 
Part I of the first paper is a review of current theories of the molecular structure of cellulose, end is included here as providing; a background against which the original research described in the later papers may be viewed; Part 2 is an attempt to interpret, in the light of these theories, the results of the studies of the chemically modified cotton celluloses that have been made at the Shirley Institute. My own contribution to this knowledge of the behaviour of chemically modified cellulose is contained in papers (2), (3) and (4). These first four Papers, which are to be regarded as the principal part of the thesis, are supported by two other papers, (5) and (6). The first of these Is a contribution to the colloid physics of cellulose. The second deals with the hydrogen ion concentration of hypochlorite solutions, a subject that is of considerable importance to cellulose chemistry, since the effect of variation of the hydrogen ion concentration on the rate of oxidation of cellulose by hypochlorite solutions and on the,character of the products provides the most important technical application of the study of the chemically modified celluloses.
