HIGH TEMPERATURE RESISTANT TRANSPARENT PLASTICS.
Abstract
Purification of the diglycidyl ether of bisphenol A by vacuum distillation and decolorization of the trimethoxyboroxine catalyst produced colorless starting materials. After curing in vacuum at 375 F for 4 hr, the 0.25 in. thick castings had a luminous transmission of 88%. In addition to an improvement of the color of the cured castings, an increase in thermal resistance was obtained. Determination of the physical properties of the vinylcyclohexene dioxide-hexahydrophthalic anhydride resins was initiated. Small quantities of low color epoxy novolac resin were obtained by molecular distillation of a commercial product. Pound quantities of the bisbicyclic diepoxides were synthesized for investigation of curing reactions and measurement of thermal properties. (Author)
