Process for the production of chloroprene polymer mixtures |
摘要 |
A process for the production of polychloroprene mixtures of sol and gel polymers in a ratio, by weight, of rom 1:4 to 9:1, the gel polymer being produced by radical emulsion polymerization from chloroprene in the presence of 4 to 10% by weight of water soluble disproportionated abietic acid, and the sol polymer being produced by radical emulsion polymerization of chloroprene in the presence of not more than 3.5% by weight of a water soluble disproportionated abietic acid with the polychloroprene mixture containing at most 3.8% of said acid.
