Rubber — Reinforced styrene-butadiene latex — Determination of total bound styrene content
Covers two methods for latices which are reinforced with polystyrene or copolymer of butadiene and styren. The two methods, the carbon/hydrogen method and the nitration method, give comparable results although they differ in principle. Either method may be used, according to preference. A table and five figures contain more details. - Constitutes a minor revision of the first edition (ISO 4655-…
