The investigation of a silicon-mediated coupling reaction between hydroxyl and carbonylimidazolide functional groups in the preparation of carbonate linkages is described. Application of this reaction to the formation of aliphatic polycarbonates was accomplished by the polymerization of an AB monome
## Abstract A new polycarbonate urethane (PCUβI) was synthesized from aliphatic monomers, i.e. polyhexamethylene carbonate diol and 4,4β²βmethyleneβbis cyclohexane diisocyanate, a mixture of low molecular diols, and castor oil (containing mainly the triglyceride of 12βhydroxyoleic acid). The second
