    Notes: Optical, mechanical, and thermal data on cold- and hot-drawn as well as crazed films of bisphenol A polycarbonate suggest that three separate processes occur during deformation. These processes are a volume change, a preferential orientation of the molecules along the deformation axis, and a configurational change within the molecules (ordering). An attempt is made to correlate these processes with the various types of experimental data. It is suggested that the ordering process is activated by surface, bulk, or external stresses, which are dependent upon molecular weight, processing history, and sample geometry.

    Notes: A detailed study of the physical properties of alternating block copolymers of polydimethyl siloxane and bisphenol-A polycarbonate is presented. The results suggest that the mechanical and optical properties of such materials are dependent upon the presence of associated regions as well as the nature of the chain between such regions. Dielectric, infrared, and DSC data as well as the stress and birefringence strain behavior are presented.

    Notes: The effect of different thermal treatments on the degree and type of orientation produced by cold drawing three polyolefin films: polyethylene, polypropylene, and polybutene-1, was studied by two complementary techniques: x-ray diffraction for the measurement of crystal orientation and birefringence for the measurement of the total film orientation. Variations in the texture of these polymer films were characterized by these techniques as well as by density, tensile stress measurements and photomicrographs. The birefringence-strain data showed a decrease in birefringence values at a given strain as the polymer side group size increased. This decrease appears to be associated with a more symmetrical polarizability ellipsoid and hence a decrease in crystal birefringence. The birefringence-strain curves for the same polymer system showed a decrease in birefringence value at a constant strain with increased annealing. X-ray diffraction data indicate that the a and b axes in both polyethylene and polybutene-1 film orient by different amounts at a given strain. Polypropylene, on the other hand, shows equal amounts orientation of the a and b axes. The different orientation behavior for these polymer systems is discussed in terms of variation in the ease with which polymer crystals may be deformed.

    Notes: In previous papers we have presented data on the dynamic birefringence and light scattering from polyethylene. New studies of the dynamic birefringence of polytetrafluoroethylene, silicone rubber, polycarbonate, polymethyl methacrylate, and polyethylene as a function of frequency and temperature have been made. The results are presented and interpreted in terms of various proposed theories. The relationships between the mechanical and optical relaxation spectrum are discussed.

    Notes: A theory of the rheo-optical properties of polyerystalline polymers has been developed. It is based on a model similar to that used by Debye for his theory of dielectric relaxation. Using the theory, sized of crystals in various types of polyethylene are calculated from rheo-optical data and compared with results obtained by x-ray techniques.
