研究了聚苯基膦酸二苯砜酯阻燃剩(SF-FR)在五十余种溶刺中的溶解性能,测定了它在不同性质溶剂中的特性粘度。用浊度法估测该聚合物的溶度参数,并用特性粘度法对其溶度参数分量进行了订定。
The solubility of diphenyl sulfone diphenyl sulfone flame retardant residue (SF-FR) in more than 50 kinds of stabs was studied. Intrinsic viscosity was measured in different solvents. The solubility parameters of the polymer were estimated by turbidity method, and its solubility parameters were determined by the intrinsic viscosity method.
