Abstract
The present invention refers to diene-based unsaturated polymer latex particles having a particle size measured as d90-value of less than 60 nm and a method for their production. Methods for using the diene-based polymer latex as rubber and for conversion to hydrogenated polymers, with reduced gel formation, are also disclosed.
