丁二烯-丙烯腈共聚物作为一种耐油性能优良的橡胶(丁腈橡胶),有十分广泛的用途.共聚物中腈基含量与其耐油、耐低温性能关系甚大,用途亦各有异.因此,在生产和使用中都须测定该共聚物中引进之丙烯腈含量.

Pyrolysis gas chromatography (PGC) equipped with carbon diozide Laser pyrolyzer was used for rapid determination of monomer component composition of acrylonitrile-butadiene copolymers. Relative ratio of peak height of the acrylonitrile to butadiene in the pyrograms exists good linear relationship with monomer component composition of the corresponding copolymers. Employing a standard curve, three samples of acrylo-nitrile-butadiene robber with unknown composition were determined conveniently, The results show that the results from laser pyrolyses agreed quite well with those from chemical analyses.
