ABSTRACT:
A polycarbonate derived from a novel dihydroxy compound having a triphenylamine structure, and a process for producing the polycarbonate are disclosed. The polycarbonate is obtained by reacting a dihydroxy compound having a triphenylamine structure described hereinbefore and a carbonate precursor, or by reacting the dihydroxy compound, a dihydric phenol compound and the carbonate precursor. The polycarbonate is useful as a plastic molding material or as a material for forming a polymer alloy with other resin.
