ABSTRACT:
Polychloroprene polymers having stable viscosities and good scorch resistance, as well as excellent mechanical and dynamic properties in vulcanized state, are prepared by polymerizing chloroprene in alkaline aqueous emulsion, in the presence of a free-radical initiator and a combination chain-transfer agent including (1) at least one xanthogen disulfide and (2) at least one bis(acylaminophenyl)polysulfide.
