A Novel Catalyst for the Preparation of Biodegradable Polycarbonate from Carbon Dioxide
A catalyst of BTPD-Zn (BTPD= N,N’-Bis(2-thiophenecarboxaldehy) o-phenylenediamine) has been found to be active toward the copolymerization of cyclohexene oxide and carbon dioxide, and a kind of good biodegradable material named poly(cyclohexene carbonate) is prepared with turnover number of 105.8 in 100°C. The molar fraction (fc) of polycarbonate in copolymer is 96%. The obtained copolymers were characterized by IR and NMR.
