Procedure

In this example a copolymer emulsion of isoprene-sodium styrene sulfonate was prepared in the same way as that of Example 1, except the recipe and reaction conditions were somewhat different. In this example the reaction was carried out at 55° C. for five hours. The various ingredient quantities were as follows. Isoprene at 1020 grams, sodium styrene sulfonate 30 gms, water 1500 gms, sodium Lauryl sulfonate 75 gms, dodecylthiol 3.0 gms and potassium persulfate 3.75 gms. The sample of this run was identified as 172-D.
