EFFECTS OF ULTRAHIGH PRESSURES ON THE FORMATION AND PROPERTIES OF ORGANIC, SEMIORGANIC, AND INORGANIC MATERIALS

Abstract

Studies on the effect of ultra high pressures (up to 90,000 atmospheres) were carried out on organic polymers and semiorganic and inorganic materials in a Belt-type internally heated high-pressure apparatus. With organic polymers, results indicate that the effect of compression is influenced by compression, compression rate, holding period, and polymer used. The most influential parameters appear to be the polymer and the holding period. Results do not show any generalized pattern and suggest that each polymer may well have its individual response to compression. Organic polymers investigated included: polyethylenes, several polyamides, polystyrene, polymethylmethacrylate, polyacrylonitrile, and ethyl cellulose.
