(57) [Summary]nA terephthaloyl moiety, optionally used other aromatic diacid moieties, an ethylene glycol moiety, an isosorbide moiety, and optionally used one or more other diol moieties, wherein the inherent viscosity of the polymer is o-chloroform at 25C. An optical article made from a clear polymer that is at least about 0.35 dL / g, measured as a 1% phenol solution (weight / volume). |
