Abstract
Process includes heating the rubber with a mixt of Zn and Mg oxides and an effective amt of a cpd. (I) as an accelerator. R = a 1-6C univalent hydrocarbon gp. free from olefinic unsaturation. With polychloroprenes not modified with S, a vulcanisation accelerator is essential to obtain the desired technical properties. Normal accelerators, used with S for hardening natural and synthetic rubbers, are not esp. suitable. A procedure is developed to satisfactorily vulcanise chloroprene rubber using (I) and a mixt. of Zn and Mg oxides.
