Chloroprene rubber CR

Commercial continuous processes have been reported for synthetic rubbers [SBR Wolk, 1959 Owen et ol.. 1947 Lundrie and McCann, 1949 Feldon et al, 1953 and CR (Chloroprene Rubber) Calcotl and Starkweather, 1954 Aho, 19583 anti a number of other polymers (Poehlein and Dougherty, 1977). As sales volumes have increased a number of industrial organizations have become interested in continuous processes and current activity in this area is significant. [Pg.358]
