Ethylene oxide and 1,2-butylene oxide were sequentially polymerised to form the diblock copolymer E13B10 (E=oxyethylene, B=oxybutylene, subscripts denote number-average block lengths in repeat units). Dynamic and static light scattering over the temperature range 10-30 degrees C demonstrated a transition from

Axonal neuropathy occurs due to occupational ethylene oxide (EtO) exposure. The experimental model of human EtO neuropathy was established. In addition, the neurotoxic effects of propylene oxide (PpO) and butylene oxide (BtO) were demonstrated in rats. Although no human neuropathy

Previous analytical studies of industrial samples of trichloroethylene (TRI) have revealed the presence of mutagenic and carcinogenic epoxides which, it was proposed, might be responsible for the carcinogenicity of such samples, as demonstrated with mice in other laboratories. To test

10 aryl propylene oxides and 6 aryl butylene oxides were synthesized. Dose-mutagenicity relationships were studied for these compounds and for 1,2-epoxybutane, using both the preincubation and plate incorporation Ames tests with Salmonella typhimurium strains TA100 and TA1535. Structure-mutagenicity relationships were
