HIGH TEMPERATURE RESISTANT TRANSPARENT PLASTICS
Abstract
Purification of the diglycidyl ether of bisphenol A (DEBA) by vacuum distillation and decolorization of the trimethoxyboroxine (TMB) catalyst produced colorless starting materials. Reaction of these materials produced a water-white resin. After curing in vacuum, the 0.25 in. thick castings had a luminous transmission of 88%. Small quantities of low color epoxy novolac resin were obtained by molecular distillation of a commercial product. The distillate reacted rapidly with TMB to form a hard solid with much lower color than obtained from any previous resin of this type. Cast resins obtained from hexahydrophthalic anhydride and vinylcyclohexene dioxide were extremely notch sensitive and brittle. (Author)
