ABSTRACT:
Oxa-organic sulfur compounds, methods of preparing such compounds and methods of using the compounds as polymer chain length terminating agents are provided. The compounds are prepared by reacting allyl alcohol in the presence of a basic catalyst with a compound having the formula ##STR1## to form an intermediate. The intermediate is then reacted with hydrogen sulfide in the presence of ultraviolet radiation and a trialkyl phosphite to form the oxa-organic sulfur compound having the formula ##STR2##
