Synthesis and characterization of some copolycarbonates of 2,2-bis (4-hydroxyphenyl)propane (bisphenol-A) and 1,4-bis(hydroxymethyl) cyclohexane

Copolycarbonates of Bisphenol-A (BPA) and 1,4-bis(hydroxymethyl)cyclohexane have been prepared. The resulting copolymers have slightly lower glass-transition temperatures than BPA polycarbonate homopolymers. Crystallisation and annealing effects are also reduced. The results are generally similar to those obtained with copolymers of BPA and 1,4-bis(hydroxymethyl)decafluorobicyclo(2,2,1)-heptane 1] but the differences are less marked.
