dc.description.abstractResearch has shown that when 40% 2,2,4,4-tetramethyl-1,3-cyclobutane diol (CBDO) is incorporated into terephthalate copolyesters, an impact resistance of 1070 J/m is measured. Cycloaliphatic monomers, like CBDO, normally are not rigid enough to produce materials with high mechanical strength. It has been postulated that the cis isomer of CBDO makes kinks in the polymer structure, which help to absorb the force upon impact and thus, improve the impact resistance of the material. This project involves the synthesis of a series of polyurethanes using CBDO and 1,3-propanediol (PDO) monomers in varying ratios. Although some of the trends observed in the thermal analysis and impact data concur with those found in the copolyester research, high impact resistances were not observed in this system.
