| Abstract: | Vinylidene fluoride-trifluochlorethylene and styrene-acrylonitrile in PBX were separated and determined by GPC with differnlial refractive detector and diode array detetor based on solubility principle. The GPC method was established to obtain the single relative molecular weight and its distribution of polymeric mixture. Compared with the raw material molecular relative weight, the separation effect is good. |
