A solid by-product formed as deposit in the pyrolysis process of poly(acrylonitrile-co-methyl methacrylate) was analyzed and two main components, namely ammonium sulphate and 1,3,5-tricyanobenzene were identified by IR, GC-IR, TG-MS and XRD methods. The main organic components, 1,3,5-tricyanobenzene was crystallized out from acetone extract as colourless needles. 1,3,5-Tricyanobenzene proved to be mutagenic by bacterial ( Salmonella typhimurium TA98 and TA1537 ) reverse mutation assay.
