Functional polythiiranes: 3. Synthesis and characterization of polythiiranes containing biphenyl units in the side chain

The synthetic route to polythiiranes bearing side chain biphenyl groups is described. [(4-Biphenyl)methylthio]methylthiirane afforded relatively low molecular weight polymers in 50% yield, while (4-biphenyl)methyl 2-[(2,3 epithiopropyl)-thio]ethanoate afforded high molecular weight polymers in high yields.
