对聚合物溶液在多釜凝聚过程的聚合物-溶剂-水多相体系的相平衡研究表明,当聚合物浓度为20％—30％(体积)时,可将聚合物溶液近似作为纯溶剂处理;聚合物种类对相平衡基本无影响。以稀土异戊橡胶的凝聚为例,建立了等速凝聚阶段和减速凝聚阶段的动力学模型。 A phase equilibrium study of a polymer-solvent-water multi-phase system in which the polymer solution is polymerized in a multi-stage reactor shows that when the polymer concentration is in the range of 20% to 30% by volume, the polymer solution can be treated approximately as a pure solvent The type of polymer has virtually no effect on phase equilibrium. Taking the cohesion of rare earth isoprene rubber as an example, the kinetic model of the isokinetic coalescence stage and the degenerate cohesion stage was established.
