Abstract
Process for preparing (co)polychloroprene rubber, comprising: PA1 a first step (a) in which a portion of a polymerizable composition is partially polymerized according to a batchwise process, PA1 a second step (b) in which the residual polymerizable composition is sequentially fed to the reaction mixture coming from the step (a), PA1 a possible third step (c) in which the reaction mixture coming from the step (b) is polymerized up to the desired conversion rate.
