Method for manufacturing polychloropren latices

摘要

Producing a latex by emulsion polymerization of chloroprene and optionally other unsaturated comonomers comprises raising the temperature by at least 3[deg] C above the starting temperature up to a conversion of 50% and then by at least 6[deg] C above the starting temperature up to a conversion of 90%. Independent claims are also included for: (1) a latex produced as above comprising a chloroprene (co)polymer with a gel content of more than 60% in toluene at 23[deg] C; (2) dispersion adhesive based on the latex; (3) foam article based on the latex; (4) fabric impregnated with the latex; (5) fibers bound with the latex; (6) bitumen or bitumen-like materials modified with the latex; (7) dip-molded article based on the latex.
