摘要

There is considerable interest in chemical modification of intact polymers (1 3). Electrophilic substitution with allylic rearrangement and loss of the silyl group is a characteristic reaction of monomeric allylic silanes. Similar reaction have not been explored with polymeric systems. Reaction of 1,4-poly(2-trimethylsilylmethyl-1-1,3-butadiene) with phenylsulfenyl chloride yields predominantly poly(3- methylene-2-phenyl-thiobutane). The mechanism of this reaction is discussed. The product polymer has been characterized by 1H 13C NMR, IR, GPC, TGA, and elemental analysis. Butadienes, Reprints, Butanes, Phenylradicals. (MJM)
