Studies on the validity of the Einstein viscosity law and Stokes' law of sedimentation
Wiley - Tập 16 Số 81 - Trang 19-30 - 1955
P. Y. Cheng, H. K. Schachman
AbstractUltracentrifugal studies on polystyrene latex particles (PSL) in solutions of different densities prepared either from mixtures of H2O and D2O or from various concentrations of sucrose in water yielded a value, by interpolation, of 1.0520 for the density of solution in which the particles neither sediment nor float....... hiện toàn bộ
Improved relationships for diffusion and sedimentation constants and for viscosity and streaming birefringence of solutions of polymers
Wiley - Tập 14 Số 74 - Trang 193-208 - 1954
Hans Kuhn, W. Kühn, A. Silberberg
AbstractFor the description of the practical properties of a large number of linear polymer molecules as well as for the discussion of the various mean parameters of the individual chain molecule, the model usually employed to represent the molecule consists of N m straight line chain elemen...... hiện toàn bộ
The infrared spectrum of polyethylene terephthalate. I The effect of crystallization
Wiley - Tập 38 Số 134 - Trang 479-495 - 1959
Akihisa Miyake
AbstractFilms of amorphous polyethylene terephthala were drawn and heated to various extents. Intensity change of the infrared spectral bands resulting from these treatments were followed. There are more than seven bands which change their intensities by drawing, and sixteen bands affected by heat treatment. Exactly the same changes are also observed in several aro...... hiện toàn bộ
Interfacial polycondensation. I.
Wiley - Tập 40 Số 137 - Trang 289-297 - 1959
Emerson L. Wittbecker, Paul W. Morgan
AbstractInterfacial polycondensation is a rapid, irreversible polymerization at the interface between water containing one difunctional intermediate and an inert immiscible organic solvent containing a complementary difunctional reactant. It is based on the Schotten‐Baumann reaction in which acid chlorides are reacted with compounds containing active hydrogen atoms...... hiện toàn bộ
Aroyl disulfides as promoter‐modifiers for copolymerization of butadiene and styrene
Wiley - Tập 3 Số 1 - Trang 58-65 - 1948
Robert L. Frank, James R. Blegen, A. J. Deutschman
AbstractBenzoyl, anisoyl, veratroyl, p‐bromobenzoyl, p‐phenylbenzoyl, p‐benzoylbenzoyl, p‐methylsulfonylbenzoyl, p(N,N‐dimethylsulfonamido)‐benzoyl and ‐naphthoyl disulfides are ...
The termination reaction in radical polymerizations. Polymerizations of methyl methacrylate and styrene at 25°
Wiley - Tập 12 Số 1 - Trang 449-459 - 1954
J. C. Bevington, H. W. Melville, R. P. Taylor
AbstractStyrene and methyl methacrylate have been polymerized at 25° using α,α′‐azo‐bis‐isobutyronitrile labeled with C14 as initiator. The numbers of initiator fragments per polymer molecule have been determined by measurements of the average molecular weights of the polymers by osmometry and the specific activities of the polymers and the ini...... hiện toàn bộ
Phenylene sulfide polymers. II. Structure of polymers obtained by the Macallum polymerization
Wiley - Tập 43 Số 141 - Trang 167-181 - 1960
Robert W. Lenz, Carl E. Handlovits
AbstractPolymers prepared by the Macallum homopolymerization and copolymerization were compared to a linear phenylene sulfide polymer prepared by the self‐condensation of sodium p‐chlorothiophenoxide. The properties compared included solubility, softening point, melting point, x‐ray diffraction pattern, infrared spectrum, and thermal stab...... hiện toàn bộ
Polybenzyl type polymers
Wiley - Tập 15 Số 80 - Trang 503-514 - 1955
Howard C. Has, D. I. Livingston, Martin Saunders
AbstractThe various proposed structures for polymers derived from benzyl type compounds have been discussed and the likelihood of these structures considered in the light of a study of their preparation and properties. Both the para substituted structure of Shriner and Berger and the pendant structure of Henne and Leicester were rejected chiefly on the basis of phy...... hiện toàn bộ
Differential thermal analysis of high polymers. II. Effects of diluents on melting behavior of polyethylenes
Wiley - Tập 50 Số 153 - Trang 79-86 - 1961
Bacon Kê
AbstractStudies of the nature and magnitude of the interaction between a polymer and a diluent are of both theoretical and practical importance. The effects of several liquid and solid diluents on the melting behavior of both high‐ and low‐density polyethylene have been studied by differential thermal analysis. The depression of melting point was related by a therm...... hiện toàn bộ
Infrared spectra of high polymers. VI. Polystyrene
Wiley - Tập 27 Số 115 - Trang 241-254 - 1958
Changhao Liang, S. Krimm
AbstractThe infrared spectrum of polystyrene has been obtained in the region of 70 cm.−1 to 3200 cm.−1. These data, plus Raman scattering data from the literature, are used to make a complete assignment of the normal modes of the polystyrene molecule. The benzene ring modes have been analyzed in detail in terms of ... hiện toàn bộ
