摘要： A RUBBER COMPOSITION CONSISTING ESSENTIALLY OF 3 TO 5O% BY WEIGHT OF A 1,2-POLYBUTADIENE HAVING A 1,2-ADDITION UNITS CONTENT OF 70% OR HIGHER AND CRYSTALLINITY OF 5% OR HIGHER, AND 97 TO 50% BY WEIGHT OF AT LEAST ONE CONJUGATED DIENE-BASED RUBBERY POLYMER SELECTED FROM THE GROUP CONSISTING OF STYRENE-BUTADIENE COPOLYMER RUBBER, POLYISOPRENE RUBBER, NATURAL RUBBER, ACRYLONITRILE-BUTADIENE RUBBE AND POLYCHLOROPRENE RUBBER. SAID RUBBER COMPOSITION HAS AN IMPROVED GREE STRENGTH, AND EXCELLENT EXTRUDABILITY, AND MOLDABILITY AND VULCANIZATES OBTAINED THEREFROM HAVE HARDNESS AND HIGH RSISTANCE TO OZONE AND WEATHERING.

摘要： A rubber composition consisting essentially of 97 to 80 percent by weight of cis-polybutadiene and 3 to 20 percent by weight of 1,2-polybutadienes having crystallinity of 5 percent or higher and a 1,2-addition units content of 70 percent or higher. Said rubber composition is prevented from cold-flow.
