抄録

Styrene polymers and acrylonitrile-styrene copolymers in dimethylformamide solution were precipitated by adding methyl alcohol. Toluene, styrene, ethylbenzene, iso-propylbenzene, and n-propylbenzene in the filtered methyl alcohol solution were determined by high performance liquid chromatography (HPLC) on a Zorbax-ODS column with a mobile phase of methyl alcohol-water (70+30) and with detection at 260nm.<br>Detection limits by HPLC were 10ppm and 500ppm in the samples analyzed for styrene and other chemicals, respectively. Recoveries of the five compounds added to the resin solution were 93-105%. Styrene in twenty-five samples was determined by the proposed HPLC method. The results are in excellent agreement with those obtained by the accepted GC method.
