    Notizen: Water absorption in thin films (〈1000 Å) of a commercial polyimide was evaluated by monitoring dimensional changes induced by a humid environment. Film thickness was measured using x-ray reflectivity, which is a nondestructive technique offering angstrom resolution in the measurements of thin film or multilayer thickness. The effect of several variables on the absorption of moisture were monitored in polyimide films adhered to polished silicon substrates, including total dry film thickness, exposure time, and the contribution of a coupling agent. The percentage increase in film thickness due to moisture uptake is found to be a weak function of dry film thickness, decreasing as dry film thickness increases, and to be somewhat affected by the use of an interfacial coupling agent. The observed behavior points to the polymer/substrate interface as a strong factor controlling the absorption of moisture in the polyimide/silicon system, and is believed to reflect the presence of a highly moisture-saturated interfacial layer. A bilayer model is proposed, and the feasibility of using this model to describe the observed behavior is considered.

    Notizen: Polyethylene single crystals deformed on copper and NaCl single-crystal substrates by the method of Gleiter and Argon were examined in transmission electron microscopy attached to carbon film carriers constraining them to their deformed state and also after they have been removed from the deformed substrates and were allowed to relax. It was observed that the imposed shear strains can be accommodated by the polyethylene crystals by a combination of debonding from the substrate, elastic flexing, extensive inplane twinning and martensitic shear transformations, buckling, and tearing. No contrast effects suggestive of slip lines could be observed in dark field studies, and the gold droplet decoration technique failed to detect any unambiguous slip lines. From this it is concluded that the critical shear stress for slip is always higher than that for twinning and martensitic shear transformations, and that crystals will deform preferentially by these latter modes.

    Notizen: Experiments were performed to determine the effects of strain rate, temperature, and pressure on the flow stress of polyethylene and Lexan polycarbonate deformed in shear. The results were analyzed to determine the activation enthalpy and the shear and dilatation activation volumes of the rate-limiting mechanism of the deformation process. Results show that the activation event involves a volume containing several monomer units and that this volume must dilate by as much as 7% during the activation event. The activation enthalpy was approximately 2.5 × 10-12 erg for polyethylene and 1.1 × 10-12 erg for polycarbonate. The rate-limiting mechanism for polyethylene seemed to be unchanged by plastic strains of up to 250%.

    Notizen: Lexan polycarbonate specimens in the form of tubes were deformed in torsion. The deformation occurs by the nucleation and growth of discrete shear bands. Shear bands are initially formed at the upper yield point. Development of the bands is accompanied by a drop in the stress to a lower yield point. At the lower yield point the strain inside the bands is approximately 70% and remains constant thereafter. Further deformation occurs by growth of the bands until they cover the entire sample. When the direction of twisting is reversed after the shear bands are formed, the deformed material untwists uniformly, without deformation in the previously undeformed material, and the stress required for untwisting the deformed material is lower than the stress required to propagate the band into undeformed material.

    Notizen: The thermodynamic treatment of crystallization phenomena in a prestretched rubber was undertaken. Emphasis was put on defining conditions for the thermodynamic stability of the extendedor folded-chain crystal structure. The extended-chain structure is found to be stable thermodynamically at temperatures higher than the isotropic melting point of un-cross-linked polymer Tm0 in the stretched state, while the folded chain one is not. Below Tm0, the stretch ratio of the network structure determines which crystal structure is more stable. The relation among the critical stretch ratio for the extended/folded crystalline structure transition, temperature, and molecular weight is also discussed. The crystallinity predicted by this work becomes zero at a temperature of Tmi, the isotropic melting point of a cross-linked system. The value of Tmi decreases with increasing cross-link density, and this is consistent with the experimental data reported in the literature.
