ABSTRACT:
1,3-Bis(4-hydroxyphenyl)-1,3-dialkylcyclohexanes, as illustrated by 1,3-bis(4-hydroxyphenyl)-1,3-dimethylcyclohexane, may be prepared by the reaction of phenol with a 1,5-dialkyl-1,4-cyclohexadiene under acidic conditions. Polycarbonates prepared therefrom have high glass transition temperatures and are expected to be ductile.
