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.
