38. 2. However, control reactions carried out under the same conditions in the presence of oxygen and without benzoquinone led only to very slow, incomplete conversions of 1 to 2.
39. 44 Moreover, because previous studies of polymers of poly(p-phenylenebutydiynylene)s have employed GPC, the method of analysis used herein allows for at least a qualitative comparison of molecular weights.

41. w = 36,300 g/mol). These lower molecular weights were, nonetheless, still considerably lower than those obtained when benzoquinone was employed as an oxidant.
42. The number-average degree of polymerization (DP) for a step-growth polymerization is equal to 1/(1 - p), where p is the extent of the reaction. For reactions that proceed to 95 and 90% completion, this corresponds to DP = 20 and 10, respectively. See Elias, H. G. An Introduction to Polymer Science; VCH: Weinheim, 1997.
43. The disparity between the predicted and observed values were accounted for by the errors associated with the use of GPC for determining the molecular weights of short, rigid-rod polymers of this type (see refs. 39 and 44). Some errors might also have arisen, however, from an incomplete reaction of benzoquinone with palladium, which would lead to lower molecular weight materials. In all other cases, benzoquinone was used in sufficient excess so that this would not be a limitation on the molecular weight obtained.
