Abstract
The conversion of (chloromethy1)thiirane to poly[(chloromethyl)thiirane] of molecular weight ca. 20 000 was accomplished by using boron trifluoride etherate as initiator. Initiators based on cadmium, zinc, or aluminum were less effective, and the anionic initiators KOH and NaNH2 produced no polymer. Poly[(chloromethyl)thiirane] was found to undergo an unusual structural rearrangement at room temperature in the absence of solvent and to hydrolyze in a dioxane/water mixture at a rate much greater than that observed for poly(epichlorohydrin). These results suggest important anchimeric assistance by the backbone sulfur atom in the reactions of poly[ (chloromethyl)thiirane].
