Abstract: By employing the present invention, a process for manufacturing products from discarded rubber and plastic material is achieved wherein compositions of vulcanized rubber and thermoplastic polymers, particularly those of the olefinic branch, are intermixed with a bonding agent to produce a processable compound having a combination of unique and unexpected properties. In the present invention, a unique bonding agent comprising a combination of ethylene co-polymers, ethylene-octane and acrylic acid is employed. By employing this bonding agent with the rubber particular and thermoplastic material, all of the prior art drawbacks are eliminated and a unique, desirable, highly useful composition is produced.

Abstract: The present invention relates to thermoplastic compositions formed from discarded rubber products. Thermoplastic compositions in accordance with the present invention comprises rubber particulate having a size less than about 10 mesh, a thermoplastic material, and at least one coupling agent with the rubber particulate and the thermoplastic material being present in a weight ratio in the range of from about 1:9 to about 9:1 and the at least one coupling agent being present in an amount less than about 3% by weight of the material to be coupled to. A process for forming the thermoplastic compositions is also described.
