Zusammenfassung:	A masterbatch composition including glass bubbles and a toughening agent in a blend of syndiotactic 1,2-poly-butadiene and cis-1,4-polybutadiene is disclosed. The glass bubbles are present in an amount of at least 25 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. A rubber composition that includes syndiotactic 1,2-polybutadiene, cis-1,4-polybutadiene, a toughening agent that includes at least one of a fluoroplastic or an organic or ceramic fiber, and glass bubbles in an amount up to 25 percent by weight, based on the total weight of the rubber composition, is also disclosed.
