通过对几种常用高聚物的改性和性能评价与对比，提出了抗温性较强的丙烯酰胺、丙烯酸、丙烯腈为基本聚合体，配以几种高温降失水剂、稀释剂进行本体聚合的合成工艺，具有聚合能量大、反应速度快、流程简便易推广的特点。还进一步探讨了ＰＡ－６型降失水剂的降失水机理。 Through the evaluation and comparison of the modification and properties of several commonly used polymers, the acrylamide, acrylic acid and acrylonitrile which are more resistant to temperature are put forward as the basic polymer, together with several high temperature fluid loss additives and diluents Bulk polymerization of synthetic processes, with a large polymerization energy, fast response, the process easy to promote features. The mechanism of water loss of PA-6 fluid loss agent is further discussed.
