    摘要
  • 摘要: 为了探究聚合物的分子结构与环保性能的关系，合成了一系列聚合物类钻井液处理剂，采用发光细菌法（EC50）和BOD5/CODCr比值评定法，研究了官能团种类、分子骨架结构及分子量等对其生物毒性和生物降解性能的影响。实验结果表明：官能团和分子骨架结构对生物毒性和生物降解性的影响较大；而分子量对生物毒性的影响较小，对生物降解性的影响较大。

     

    Abstract: A series of drilling fluid polymers were synthesized to investigate the relationship between the molecular structure and environmental friendliness of drilling fluid polymers. Using the luminescent bacteria method (EC50) and BOD5/CODCr ratio method, the effects of the type of functional groups, the backbone structure of molecules and molecular weight on the biotoxicity and biodegradability of a polymer was studied. It was found that functional groups and backbone structures of a molecule play the major role in the magnitude of biotoxicity and biodegradability, the molecular weight of a polymer, on the other hand, has minor impacts on its biotoxicity and major impacts on its biodegradability.
