Abstract
A process for the preparation of alkylene episulfides or episelenides is provided which comprises contacting elemental sulfur or elemental selenium, respectively, with an olefin, preferably ethylene, while irradiating with electromagnetic radiation in the infrared to ultraviolet range. The alkylene episulfides and episelenides are useful in the production of a variety of functional polymers.
