Most current EM embedding media require component mixing prior to use. Also, many epoxy resins are carcinogenic and can present significant health hazards in the unpolymerized form. LR White acrylic embedding resin(by London Resin Co.; available Fullam, Pelco, Polaron etc.) is a one component, extremely low viscosity resin. The resin, according to Mfr. has a very low toxicity both in monomeric and polymerized states. We have found no skin sensitivity specifically known to be related to the resin over a period of 1 yr routine resin use. The cold cure accelerator does have some toxic risk, and contact with skin and eyes should be avoided. Accelerator, however, is not used for thermal curing. Because of resin advantages, the purpose of this study was to determine routine TEM methods consistent with LR White resin use for a variety of sample types(fungal, plant, and animal).

The formation of amines by the photolysis of O-acyloximes derived from acetophenone oxime, benzophenone oxime, fluorenone oxime, and 2-acetonaphthone oxime and the curing of epoxides by the resulting amines were investigated. The quantum yields of their photolysis at 366 nm in polystyrene films depend on their structures, and those for bifunctional ones bearing phenyl or naphthyl moieties were found to be very high, at 0.88 and 0.76, respectively. The yields of the resulting amines in polymer matrices were higher than those in solution. The yields for O-acyloximes bearing a naphthyl moiety were ca. 90% and higher than for those bearing a phenyl moiety. Although the resulting amines were efficient photo-cross-linkers for poly(glycidyl methacrylate), they were not effective for curing of epoxy resins (oligomers). On the other hand, polymer amines with a glass transition temperature lower than room temperature, which were obtained by the photolysis of copolymers bearing acyloxyimino groups, were found to be effective photo-cross-linkers for the epoxy resins. Keywords: photo-base generator, acyloxyimino group, photo-initiated and thermal curing, poly(glycidyl methacrylate), epoxy resin.
