ABSTRACT:
The novel process provides latices of homo- and copolymers of chloroprene and of one or more further copolymerizable monomers at a higher reaction rate and hence in an improved space-time yield. The latices obtained have a high gel content, distinctly lower levels of by-products, in particular of chloroprene dimer, than prior art products, and are useful, if appropriate in concentrated form, for a wide variety of applications.
