Significant alteration of the properties of legacy step-growth polymers ,  e.g. polyesters, polyamides, polycarbonates, and poly(arylene ether sulfones)  generally requires the copolymerization of a new monomer into the backbone.   Our recent research has focused on inserting new 1,4-cyclohexylene based monomers into PAESs.  Among other approaches, a new bisphenol, 4,4'-[trans-1,4-cyclohexanebis(methylene)] bisphenol (CMB) was synthesized and copolymerized into the PAES backbone.   Surprisingly enhanced elongation to break values were observed when CMB was copolymerized with 4,4'-dihydroxy-p-terphenol.
