Biodegradation of Styrene-Maleic Anhydride Copolymer
-
摘要: 合成了一系列苯乙烯.马来酸酐共聚物(SMA)。并对共聚物的结构进行了表征。用土埋法和CO2释放法研究了共聚物的生物降解性。探讨了分子量、组成、环境等因素对生物降解性的影响,发现共聚物的分子量降低。降解率增大;共聚物中马来酸酐含量提高。降解率增大;适宜的环境有利于生物降解。Abstract: Poly (styrene-co-maleic anhydride) was synthesized by solution copolymerization. The structure of the copolymer was characterized by FTIR and ~1H-NMR. An attempt has been made to give biodegradability to the copolymer which showed degradation by CO_2 rele
