摘要： A polychloroprene of sol type, the latices and solutions of which are gel free, exhibit improved rheological and other properties and are useful in the formulation of adhesive compositions, is readily prepared by polymerizing chloroprene in aqueous emulsion in the presence of X and Y chain transfer agents, said X chain transfer agent being present upon initiation of the polymerization and having a relative reaction velocity greater than that of chloroprene, and said Y chain transfer agent being incrementally or continuously added to the polymerization reaction medium over the course of the polymerization reaction and having a relative reaction velocity essentially the same as that of chloroprene.
