| 中文摘要 | a convenient one-pot terpolymerization of co2, propylene oxide (po), and l-lactide (l-la) in short polymerization time (10 h or shorter) to afford poly(propylene carbonate-lactide) with excellent mechanical property and thermal stability using y(ccl3coo)3-znet2-glycerin rare-earth ternary catalyst is reported. the yield of the copolymerization was between 69.7 and 111.7 g/(g zn), corresponding to l-la/po molar feed ratio varying from 0 to 0.1, and the number average molecular weight was between 5.5x104 and 11.9x104. the l-la content in the terpolymer increased from 1.1% to 34.7% when l-la/po molar feed ratio changed from 0.01 to 0.1. introducing l-la as the third comonomer could significantly improve the mechanical strength and thermal stability of ppc. for the terpolymer obtained from l-la/po molar feed ratio of 1:50, the elongation at break reached 40.5%, which is 3 times of that of pure ppc, and the thermal decomposition temperature increased by 32 degrees c compared with pure ppc. |
