Conformational Energy Calculations in Isotactic and Syndiotactic Polymers... [Pg.71]

An expression for M for an atactic aryl vinyl polymer generally cannot be written in closed form, because the nonzero values of kin> permit a make-and-break form of energy migration. However, if kJn,/kD syndiotactic triads by taking kr>M — 2 koMmeJO kDM,m o + koM.dii and 2khM,di. respectively. The value of M for the polymer is then obtained by averaging over the triad population of the polymer. [Pg.69]

Calculations have been carried out for poly[(5)-l-methylpropyl vinyl ether] and poly[(S)-2-methylbutyl vinyl ether] using properly estimated conformational energy parameters. The characteristic ratios C obtained are shown in Figure 6(a). For the former polymer, large enhancement in Cqo is predicted both in the isotactic (Pr>0.8) and in the syndiotactic Pr<0.2) region. [Pg.63]
