Abstract

Polybenzopinacols resulting from the photocondensations of p,p′‐dibenzoyldiphenyl ether, p,p′‐dibenzoyldiphenylmethane, and p,p′‐dibenzoyl‐1,2‐diphenylethane were rearranged in sulfuric acid–dioxane solutions. The inherent viscosities of the polybenzopinacolones did not differ significantly from the inherent viscosities of the polybenzopinacols after rearrangement. A model compound study by NMR and infrared methods indicated that the polymer chain was probably the main migrating group for each of the polymer rearrangements.

The presence of a &-butyl group ortho to another substituent on an aromatic ring causes appreciable steric strain in the molecule. The strain energy in o-t-butylto--luene has been estimated to be around 4-6 kcal./mole,1,2 while the presence of a se-
