高抗冲聚苯乙烯是由苯乙烯与顺丁橡胶采用本体-悬浮法接枝共聚制得,主要用于制作浅色制品。因此,高抗冲聚苯乙烯的色度是一个重要的指标,为保证产品质量,首先要对顺丁橡胶、苯乙烯溶液的色度进行测定,本标准主要介绍顺丁橡胶溶液色度的测定方法。顺丁橡胶溶液色度测定方法标准制定工作的主管部门是中国石化总公司,技术归口是全国橡标委合成橡胶分技术委员会,负责起草单位是兰化公司研究院,参加起草工作的单位有:燕山石化公司合成橡胶厂、兰化
High impact polystyrene is made of styrene and butadiene rubber using bulk - suspension graft copolymerization, mainly for the production of light-colored products. Therefore, the color of high impact polystyrene is an important indicator, in order to ensure product quality, we must first of the butadiene rubber, styrene solution, the determination of the color, this standard mainly describes the determination of the color of butadiene rubber solution method. Butadiene rubber solution colorimetric determination of the standard-setting department in charge of the work is the China Petrochemical Corporation, the technical focal points of the National Committee of the NomCom rubber sub-technical committee responsible for the drafting unit is Lanhua Research Institute, to participate in the drafting of the work units are: Yanshan Petrochemical Company Synthetic Rubber Factory, Lan
