The method is applicable to laticescontaining boric acid. The method is not applicable tolatices preserved with potassium hydroxide. It is notnecessarily suitable for latices from natural sourcesother than Hevea brasiliensis, or for latices of syn-thetic rubber, compounded latex, vulcanized latex orartificial dispersions of rubber.【中国标准分类号】: B72【国际标准分类号】: 83_040_10【页数】: 9P.;A4【正文语种】: 英语
