<p>PROCESS FOR PRODUCING FIBER-REINFORCED ELASTIC ARTICLES Disclosed is a process for producing fiber-reinforced elastic articles comprising: 1 to 20 parts by weight of 1,2-polybutadiene fibrils dispersed in a matrix of 100 parts by weight of a rubber material. In the process, the 1,2 -polybutadiene in the form of particles are dispersed in the matrix of rubber material; the dispersion is extruded through a die at a temperature of at least 5.degree.C above the melting point of 1,2-polybutadiene, but not exceeding 240.degree.C, to convert the particles of 1,2-polybutadiene into fibrils; the extruded dispersion is rolled by means of a pair of rollers to increase the degree of molecular orientation of the 1,2-polybutadiene fibrils, and; a composition comprising an elastic material matrix, the 1,2-polybutadiene fibrils dispersed in the elastic material matrix and a vulcanizing agent is shaped and vulcanized at an elevated temperature.</p> |
