The procedure may give low results when the content of mineral fillers insoluble in nitric acid exceeds 5 % (m/m). The principle is based on the extraction of a test portion with acetone and digestion with nitric acid to oxidize the styrene to p-nitrobenzoic acid. Extraction of the p-nitrobenzoic acid
