scope:

Specifies a method for the determination of butadiene monomer in polymers. The method is applicable to acrylonitrile-styrene copolymer (ABS) and to high-impact polystyrene (HIPS) as well as to other 1,3-butadiene polymers and copolymers where these are soluble in N,N-dimethylacetamide or finely dispersed, swollen suspensions in N,N-dimethylacetamide. The level of 1,3-butadiene monomer determined is expressed as milligrams of 1,3-butadiene per kilogram of polymer. The method is appropriate for the quantitative determination of 1,3-butadiene at a level of 0,1 mg/kg in the polymer.
