摘要:
A method is described for the determination of microcrystalline wax in butadiene-styrene copolymer pellets at levels ranging from 0.10 to 0.55 wt. %. Polymer pellets are contacted with hot isooctane. The mixture is cooled and the solvent decanted. Following further cooling, the turbidity of the extracted solution is measured. The amouit of microcrystalline wax is calculated using a calibration curve derived from prepared standards. The limit of detection is 0.1% microcrystalline wax, due to sample background turbidity.
