Abstract: This invention discloses an aqueous slurry for coating the surface of rubber slabs or pellets to reduce the tendency of the rubber slabs or pellets to stick together, said aqueous slurry being comprised of (1) from about 1 weight percent to about 15 weight percent of syndiotactic-1,2-polybutadiene having a melting point of no more than about 140.degree. C. and a particle size of no more than about 40 mesh; (2) from about 0.1 weight percent to about 5 weight percent of a suspending agent; (3) from about 0.05 weight percent to about 2 weight percent of a wetting agent; and (4) from about 78 weight percent to about 98 weight percent water. The present invention further reveals a coated rubber slab having resistance to sticking which is comprised of a rubber slab having a coating thereon, wherein said coating is comprised of syndiotactic-1,2-polybutadiene having a melting point of no more than about 140.degree. C. and a particle size of no more than about 40 mesh.
