| 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 release test and soil burial test. The results showed that biodegradation of the copolymem increased with the decrease in copolymer molecular weight. The experiments also indicated that the copolymer degraded faster under some suitable circumstances. |
