| 摘要 | In order to recover propylene carbonate (PC) from waste lithium-ion battery electrolyte, the electrolyte was coupled with dimethyl succinate (DMSu) to prepare degradable polyester PPS. To further enhance the performance of PPS, ethylene glycol (EG) was introduced to prepare copolyester PPSG, and the effects of the amount of added EG on the performance of copolyester were explored. The results show that the synthesized polyester was the target product. With the increase in the amount of added EG, the molecular weight of the copolyester gradually rose, but the glass transition temperature (Tg) of PPSG gradually decreased, and the degradation rate was significantly faster than that of PPS. Within 24 d, the mass loss rate of PPSG-30% reached 75.8%. |
