propylene oxide (PO) and isocyanates was studied. In this paper
the dependence of the yields
intrinsic viscosity and their distribution as well as thermal stability of the terpolymers on the reaction conditions and isocyanate content were described. The addition of isocyanates resulted in chain extending
branching and crosslinking. The experimental results showed that the copolymerization produced polyimidocarbonates instead of the polyurethanes. The terpolymlers were thermally more stable than the copolymer of CO2 and propyleneoxide.
