Amalgamation of polymer materials
First Claim
1. A method of producing a formable material of dissimilar thermoplastic polymers comprisingmixing fragments of said dissimilar thermoplastic polymers into a mixture,intermixing a small percentage by weight of particles of blown asphalt into a combination with said mixture,heating and working said combination into an amalgamation of said polymers,and further processing said amalgamation into products.

Abstract
A method of producing formable material of dissimilar polymers and the amalgamated product produced thereby in which mixed thermoplastic polymers have a small percentage of blown asphalt combined therewith, the asphalt acting somewhat as a flux to promote commingling and amalgamation of the polymers during processing to form a product as in extrusion and injection molding operations.
