DEPOLYMERIZATION OF POLYMERS

DEPOLYMERIZATION OF POLYMERS

A method of depolymerizing formulated rubbers and polymer solids is described. The method utilizes a solvent at or above the solvent's critical pressure and critical temperature with a low ratio of solvent to the solid material. The resulting depolymerized material in either substantially solid...

Zusammenfassung:A method of depolymerizing formulated rubbers and polymer solids is described. The method utilizes a solvent at or above the solvent's critical pressure and critical temperature with a low ratio of solvent to the solid material. The resulting depolymerized material in either substantially solid or highly viscous liquid form can be repolymerized with the addition of more monomer.
