Composite Processes from PEI/TLCP Blendsdulus characteristics.. In this composite, the thermotropic liquid crystalline polymer (TLCP) reinforcing agent comes out as a low viscous melt during the compounding process, and crystallizes upon cooling to form needle-like reinforced structures in the final fabrication step. This . composite proc

Improved Elastomers through Control of Network Chain-Length Distributionsf two primary reasons. On the experimental side, the cross-linking techniques traditionally used to prepare the network structures required for rubberlike elasticity have been random, uncontrolled processes.. Examples are vulcanization (addition of sulfur), peroxide thermolysis (free-radical couplin

Surface Properties of Silicone High Voltage Insulators given by Gorur and Orbeck. as light weight, superior vandal resistance and better contamination performance. However, polymers are more easily degraded than inert inorganic materials under exposure to discharges and arcing. Corona discharges and dry band arcing occur when the surface of an energize

Recent Development of Chemical Resistant Styrenic Polymers for the Refrigeratorcountry. All the materials and the processes using CFC11 have been destined for change. Refrigerator is an example. As a blowing agent, CFC11 has long been used. Recently HCFC-141b and cyclopentane are being used as alternatives. However, the former deteriorates the mechanical properties of current

Simulations on Thermoplastic Elastomers from Polypropyleneere also used to investigate the development of reinforcing crystallites in thermoplastic elastomers. New types of stereoblock polypropylene which have been prepared from some metallocene catalytsts and which function as thermoplastic elastomers through controlled crystallization are of particular i

Study of Energy Gap and Electronic Transitions in Model Polymer Systems: Electronic Versus Optical ESpectroscopy); when applied to study polymers and related advanced materials, it allows to characterize the material energy gap and its electronic transitions. Four sample cases are presented: the measurement of electron induced radiation damage in polyethylene, the study of the energy gap of C., th
