NEW CATALYTIC SYSTEMS FOR THE FIXATION OF CO2 Ⅲ.INFLUENCE OF ADDITIVES AND REACTION MEDIUM ON THE COPOLYMERIZATION OF CARBON DIOXIDE-EPICHLOROHYDRIN IN THE PRESENCE OF Nd (P204)3-Al(i-Bu)3*

Received Date: 10 June 1992

Copolymerization of carbon dioxide with epichlorohydrin was successfully carried out by usingNd(P204)3-Al(i-Bu)3 as catalyst (P204)=(RO)2 POO--,R=CH3 (CH2),CH(C2H5) CH2--). Addi-tion of carbonyl compounds into the catalyst decreased the carbon dioxide content of the copoly-mer to some extent. Compared to nonpolar solvents, ethereal and moderate polar solvents werefavourable to obtaining higher carbon dioxide content copolymer. The coincidence of these resultswith the assumed copolymerization scheme clearly indicated that the copolymerization proceeds via coordinate anionic mechanism.
