## Abstract Carbon dioxide (CO~2~) as a direct material was copolymerized with epoxides to synthesize new aliphatic polycarbonates, and the copolymerization was catalyzed by the coordinate catalyst composed of rare earth yttrium phosphonate and triisobutylaluminum [Y(P~204~)~3~βA1(iβBu)~3~]. The ep
## Abstract Propylene oxide and cyclohexene oxide were copolymerized with carbon dioxide in the presence of catalysts such as diethylzinc with phenol or 1βphenoxyβ2βpropanol and/or a polyhydric phenol (polyhydroxybenzene derivatives such as 4β__tert__βbutylcatechol, pyrogallol): The corresponding c
