IS 4511 : Part 3 : 1987 Methods of Test for Styrene-butadiene Rubber (SBR) Latices - Part 3 : Determination of Volatile Unsaturates

1 Scope

1.1 This standard (Part 3) prescribes a method for thedetermination of volatile unsaturates in styrene-butadiene rubberlatices.

1.2 This method measures, in addition to residual styrene, otherunsaturates such as butadine dimer.
