ABSTRACT:
A heterocyclohexylidenebisphenol having the formula ##STR1## wherein X is S, SO, SO.sub.2 or N--OCOR and R is a C.sub.1-4 primary or secondary alkyl or phenyl optionally substituted by an ethyl or 1-2 methyl groups may be prepared by the reaction of bisphenol A or a similar compound with the corresponding thiopyranone or piperidone. The thio compound may be oxidized to the corresponding sulfone. Polycarbonates prepared from said heterocyclic bis(4-hydroxyphenyl)cycloalkanes have high glass transition temperatures and are expected to be ductile.
