How does a 1,3- butadiene get converted to cis-2 butene during styrene-butadiene free radical cold emulsion polymerization?

We specialize in a styrene-butadiene emulsion polymerization, we run conversion to 60% and we recover the unconverted (1,3- butadiene) at a purity of average of 73% and major impurity is (cis-2...
