摘要

Process for the production of neodymium catalyzed polybutadienes (ndbr), rubber mixtures containing neodymium catalyzed polybutadienes (ndbr), and uses of rubber mixtures The invention relates to neodymium catalyzed polybutadienes (ndbr) comprising 95% by weight of cis-1,4 units and 1% by weight of 1,2-vinyl content, based on neodymium catalyzed polybutadienes, where ndbr shows a molar mass fragmentation of at least 25%. 1/1
