Summary
In the present study, three methods of introduction of the tartaric acid derivative into poly(carbonate-urethane)s chemical structure are presented and discussed. Tartaric acid derivative containing two free and two protected OH groups was introduced according to polycondensation, ring opening polymerization (in oligocarbonate synthesis step) and polyaddition (in prepolymer synthesis step as achain extender) reactions. The prepared poly(carbonate-urethane)s were characterized by NMR and FT-IR spectroscopies, DSC and TGA thermal analyses, and mechanical properties measurements. The influence of the introduced tartaric acid derivative on properties of oligocarbonates and polyurethanes was investigated.
Keywords: poly(carbonate-urethane), oligocarbonate diol, tartaric acid, (4S,5S)-4,5-bis(hydroxymethyl)-2,2-dimethyl-1,3-dioxolane
