16. Under the conditions at 60°C for 12 h the 2 did not convert completely. As a control experiment the polymerization of 2 was carried out under the same conditions and the product was isolated without the further addition of 3A. In this case the poly(2) was obtained in a 60% yield, which consisted of 1,4-czs (65%) and 1,4-frans units (35%), respectively.
17. The substantial broadening of the molecular weight distribution of 5A is ascribable to the nature of the polymerization process of 2 (vide supra). This trend is also clearly observable in the homopolymerization of 2. See, for example, the PDI of . poly(2) in Table I runs 3 and 4. See also réf. 5.
