| 英文摘要 | Highly alternating co2-cyclohexene oxide copolymer, namely poly(cyclohexene carbonate) (pchc), considered potentially to be microelectronic sacrificial material, was successfully synthesized by copolymerization of cyclohexene oxide and co2 in the presence of salenal((opr)-pr-i) catalyst. the obtained highly alternating pchc copolymer were determined and proven to have superior thermal decomposition properties decomposing completely at 350 degrees c by thermogravimetric (tg) analysis under dynamic conditions. the thermal decomposition kinetics of the obtained pchc was investigated by a different kinetic method using data from tg analysis. based on the analytical, kinetic parameters were calculated and kinetic model of pyrolysis was proposed. tg-ir, py-gc/ms, ir and h-1 nmr techniques were applied to investigate the decomposition process. based on py-gc/ms and tg-ir techniques, carbon dioxide, 1,3-cyclohexadiene, cyclopentanecarboxaldehyde, cyclohexene oxide, cyclohexanone and trans-1,2-carbonyldioxycyclohexane were identified as thermal decomposition products of pchc. the solid residues of the pchc with 25% ether linkages decomposed at 200, 250, 300, 350 degrees c as determined by ir and h-1 nmr. the results demonstrated that the carbonate content of the solid residues decreased gradually at elevated heat-temperatures and at 350 degrees c only few polyether linkages were observed. |
