标准范围

本文件规定了测定苯乙烯-丁二烯橡胶（SBR）晶格的结合苯乙烯含量的方法。该方法适用于热(约50℃)乳液聚合SBR晶格，其结合苯乙烯含量(以SBR含量表示)高达55？%和冷(约5？℃)乳液聚合SBR晶格，其结合苯乙烯含量在18？%和40？%.该方法不适用于增强丁苯橡胶(SBR.Y)晶格、羧基丁苯橡胶(XSBR)晶格和吡啶丁苯橡胶(PSBR)晶格。

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.
