A masterbatch composition including glass bubbles dispersed in a blend of syndiotactic 1,2-polybutadiene and cis-1,4-polybutadiene is disclosed. The glass bubbles are present in an amount of at least 30 percent by weight, based on the total weight of the masterbatch composition. A method of making a rubber composition from the masterbatch composition is disclosed as well as a rubber composition and vulcanized rubber made from the masterbatch composition. Se describe una composición de mezcla madre que incluye burbujas de vidrio dispersas en una mezcla de 1,2-polibutadieno sindiotáctico y cis-1,4-polibutadieno. Las burbujas de vidrio están presentes en una cantidad de al menos 30 por ciento en peso, con base en el peso total de la composición de mezcla madre. Se describe un método para elaborar una composición de caucho a partir de la composición de mezcla madre, así como una composición de caucho y caucho vulcanizado elaborados a partir de la composición de mezcla madre.
