摘要
为了较好地解决泥页岩井壁稳定问题,研究了一种以淀粉、氯丙烯、二乙胺和其它烯类单体为原料,以硝酸铈铵(CAN)和乙酰乙酸乙酯(EAcAc)作引发剂而合成的阳离子淀粉—烯类单体接枝聚合物OCSP。讨论了氯丙烯、NaHCO_3及水对有机阳离子(OC)转化率和岩屑回收率的影响,以及引发剂加量和OC加量对OCSP抑制性的影响。结果表明,NaHCO_3和水是影响OC转化率的关键因素;OCSP不仅具有良好的抑制性而且还能与部分处理剂配伍。
The preparation of OCSP comprises the step of (1) the synthesis of organic cationic intermediate product (OC) from chlorallylene and diethylamine , (2) pasting of starch , (3) polymerization of OC , starch and other allyl monomer . The initiating agents for this reaction are cerous ammonium nitrate , ethyl acetoacetate . The influence of various factors on production rate is discussed . OCSP is environmental safe .
