本欧洲标准的这一部分规定了聚合物中丁二烯单体的测定方法。 该方法适用于丙烯腈 - 丁二烯 - 苯乙烯共聚物（ABS）和高抗冲聚苯乙烯（HIPS）以及其它可溶于N，N-二甲基乙酰胺或精细分散的1,3-丁二烯聚合物和共聚物，溶于N，N-二甲基乙酰胺的悬浮液。所测定的1,3-丁二烯单体的含量表示为每千克聚合物中的1,3-丁二烯的毫克数。该方法适用于在聚合物中以0.1mg/kg的水平定量测定1,3-丁二烯

This part of this European Standard specifies a method for the determination of butadiene monomer in polymers. The method is applicable to acrylonitrile-butadiene-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.
