“…Blaker and Badger [817] have studied the thermodynamic interaction of nitrocellulose with various organic liquids by a light-scattering technique, while Ermolenko and Levina [831~ have investigated the effect of non-solvent on the structural viscosity of cellulose acetate solutions. Brice, Halwer, and Speiser [819] have described a photometer for measuring turbidity, dissymmetry, and depolarization of dilute solutions of high-molecularweight materials.…”

This paper is a review of the literature published during 1950 in the field of textile science and technology. The breadth of the subject matter in pure science and in technology represented by the extensive bibliography indicates the many important fields in which the textile industry is now devoting effort and which it must follow closely if improvements in processing operations and in materials are to be translated into more useful products for the con-sumer.Papers in the field of research have been concerned with studies of the structure and properties of natural and synthetic fibers, with the chemistry of cellulose and starch, with the microbiological degradation of cellulose and wool, and with the processes of adsorption, swelling, diffusion, dyeing, and detergency. Certain general papers in the field of high polymers have been included because the techniques are important in textile research. Methods for determining molecular weight by viscometry, osmotic pressure, light scattering, and centrifugation have been reviewed. New equipments and techniques for the control of processing and laboratory equipment and for the test, identification, and examination of textile materials have been considered.In the field of development, the papers in the literature have reported on improved processes for opening and blending, carding, drafting, spinning, winding, weaving, and knitting. In wet processing attention has been given to scouring, sizing, dyeing, and printing, bleaching, and stripping. The literature on finishing includes studies of dimensional stabilization of fabrics, flame-resistance, waterproofing, resin finishes, and coating materials.II. Introduction ' The material reviewed in this paper has been selected from the scientific and technical journals published in the United States and abroad, and from certain standard abstract journals. It is believed that this review covers the important contributions in the fields of textile research and development during 1950; however, certain papers assembled at the outset have been omitted because they were considered inappropriate. The material in the text has been divided somewhat arbitrarily into the fields of research and development, and into sub-classifications of these divisions controlled principally by the published literature.The bibliography has been arranged to conform with the main divisions and their sub-classifications. The individual papers cited are numbered consecutively in the bibliography; the papers in each of the principal sections in research and development are arranged in alphabetical order by first author. The numbers in brackets in the text refer to the appropriate papers in the bibliography. III. Review Papers of General InterestThe general literature on textiles during the past year includes the publication of many books and scientific papers which are not concerned with particular materials or processes but deal in a broad way with the textile field. These publications treat such subjects as the general progress in research and develop...

“…The size of the coiled polymer is determined by the length of the polymer chain and, accordingly, the molar mass of the polymer. The application of this method is currently not limited to measuring only the molecular parameters of polymers but also includes the determination of other important characteristics, such as the size and shape of macromolecules, polydispersity of the sample, and thermodynamic parameters of intermolecular interaction [ 44 , 45 , 46 ].…”

Special Aspects of Nitrocellulose Molar Mass Determination by Dynamic Light Scattering

2023

The dynamic light scattering method was successfully applied to determine the molar mass of nitrocellulose. The methodology of nitrocellulose fractionation in acetonic solutions is described in detail; six polymer fractions with monomodal distribution were obtained. It was shown that the unfractionated colloxylin with polymodal molar mass distribution had mass average molecular mass values of 87.3 ± 14.1, 28.3 ± 7.3, and 0.54 ± 0.17 kDa when investigated by the dynamic light scattering method. The viscometric method only provided integral viscosity average molar mass equal to 56.7 ± 5.8 kDa.

Light‐scattering and viscosity measurements were obtained for seven fractions of the diethylacetamide derivative of cellulose xanthate (DAX) in 90% dimethyl sulfoxide. The degree of substitution (D.S.) range represented by the samples was 0.4 to 1.22; the molecular weight range was 112,000 to 446,000. The following empirical equation between the intrinsic viscosity and D.P.w was found: [η] = (5.63 – 3.35 D.S.) × 10−3 D.P.w. As reflected by the km– D.S. plot, the Martin constants, and the configuration parameters, it was apparent that the low D.S. derivatives are considerably more extended in solution than high D.S. derivatives of the same chain length. Under such conditions, it is apparent that solvent‐polymer interaction has assumed an important role in determining the polymer configuration. The behavior of the DAX molecule in solution was found to be strikingly similar to that of other cellulose derivatives. Hydrodynamic considerations revealed that the behavior in solution appears to approach that of the more flexible synthetic polymers at D.S. levels above 0.9 and molecular weights above 400,000.
