p- (β-Bromoethyl) benzyl chloride was treated with sodium alcoholate at room temperature to obtain p-vinylbenzyl ether, which could be polymerized in bulk using 2, 2'-azobisisobutyronitrile as an initiator.

Sodium tert-butyrate failed to give the expected tert-butyl ether. Instead, p-chloromethylstyrene was the only product isolated.
Using sodium mercaptide under analogous conditions, p-vinylbenzyl sulfide was synthesized, from which a new polymer was obtained as follows ;
