摘要
Abstract
The poly(L-lactic acid)(PLLA) cast film was made using purified PLLA and calcium chloride, the purified CHCl3 acted as solvent.The specimen was investigated by modulated thermogravmitry analysis, the results showed the PLLA pyrolysis had one step, at the same time we got the Ea, Z and ln(rate ratio).The structures low molecular compounds were determined by NMR and FTIR.The data supported that during the pyrolysis process,the furan, cyclopropanes and lactic acid were produced except low molecular PLA.关键词
