Abstract
A composition containing reclaimed vulcanized rubber particles and capable of being recycled by melting is disclosed. A thermoplastic substrate is first melted, and an acid or base deflocculant and emulsifier for the rubber particles is added and mixed. The rubber particles are then added and heated with the substrate under high shear forces to redo the size of the particles, cause them to swell, and to emulsify the surface. The acid or base deflocculant is then neutralized to its isoelectric point, with the surfaces of the altered rubber particles in phase with the thermoplastic substrate.
