Abstract
A process for preparing a mixture of rubbers characterized by mixing at least 10 parts by weight of a polybutadiene containing at least 75% cis-1,4-butadiene addition and either (a) natural rubber, or ( b) a styrene butadiene copolymer 75/25 formed by emulsion polymerization, or (c) a cis-polyisoprene containing at least 75% cis-1,4-isoprene addition, said figures being based on parts by weight over 100 parts by weight of the total rubber in the mixture.
