Sumary: Phenylacetylenes (PhCXQ with Q = PhS02, I, SPh, 8u3Sn PhC$Hg) undergo free radical chain substitution reactions with RHgCl, R2Hg, (Et0)2P(O)HgCl, (PhS)2Hg or (PhS02)2Hg. The relative reactivities of PhCXQ towards c-C6HII\* are Q = PhS02 (65) > I (19) > Bu3Sn (1.0).

The radical polymerization of dicyclohexyl fumarate (DCHF) and its derivatives was carried out with dimethyl 2,2'-azobisisobutyrate in benzene at 60Β°C. The propagation and termination rate constants (kp and kl) were determined by electron spin resonance spectroscopy. The k, and k, values were 0.48-0
