Abstract
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.
