摘 要: 提出了一种用化合物的无机值(I)和有机值(O)设计水溶性聚合物和选择助溶剂的新方法。聚合物溶于水的条件是其I/O>1,理想助溶剂的I/O应该与聚合物的I/O接近。试验结果证明该判据是正确的。 A novel method for designing water-soluble polymer molecules and selecting cosolvents by using inorganic(I) and organic(O) values of compounds was put forword, this is, I/O of water-soluble polymers should be more than l, I/O of an ideal cosolvent should be closed to that of the polymer. The results of test support the criterion and show that viscosity-peak phenomenon of the aqueous solution of polymers is caused by poor water-solubility of polymers. The method may be used for development of waterbased polymer products such as paints, adhesives.
