标准摘要
[中文适用范围]： 本文件规定了丁苯橡胶 (SBR) 胶乳中结合苯乙烯含量的测定方法。 该方法适用于热（约 50 °C）乳液聚合 SBR 胶乳，其结合苯乙烯含量（以 SBR 含量表示）高达 55%，也适用于冷（约 5 °C）乳液聚合 SBR 胶乳，其具有结合苯乙烯含量在18%到40%之间。 该方法不适用于增强丁苯橡胶（SBR..Y）胶体、羧基丁苯橡胶（XSBR）胶体和吡啶丁苯橡胶（PSBR）胶体。 [外文原描述]： This document specifies a method for the determination of the bound styrene content of styrene-butadiene rubber (SBR) lattices. The method is applicable to hot (approximately 50 °C) emulsion polymerized SBR lattices having a bound styrene content, expressed on the SBR content, of up to 55 % and to cold (approximately 5 °C) emulsion polymerized SBR lattices having a bound styrene content between 18 % and 40 %. The method is not applicable to reinforced styrene-butadiene rubber (SBR. .Y) lattices, carboxylic-styrene-butadiene rubber (XSBR) lattices and pyridine-styrene-butadiene rubber (PSBR) lattices.
