ABSTRACT:
A heterocyclohexylidenebisphenol having the formula ##STR1## wherein X is S, SO[,] or SO.sub.2 [or N--COR 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 phenol or a similar compound with the corresponding thiopyranone [or piperidone]. The thio compound may be oxidized to the corresponding sulfoxide or sulfone. Polycarbonates prepared from said heterocyclic bis(4-hydroxyphenyl) cycloalkanes having high glass transition temperatures and are expected to be ductile.
