Patent ID: 7309744

Claim:
An article of manufacture made by the process comprising: A. mixing: a. an isotactic polymer; b. a cross-linking agent, wherein the cross-linking agent comprises a peroxide and a sulfur, wherein the peroxide comprises an activity ranging from about 40% to about 100%; and c. an accelerator that is tetramethyl thiuram monosulphide or tetramethyl thiuram disulphide, wherein the ratio of the accelerator to the sulfur ranges from about 1:4 to about 1:10 depending on the activity, and wherein the ratio of the accelerator to the peroxide ranges from about 1:4 to about 1:10 depending on the activity, B. shearing the isotactic polymer in a high shear rate mixer with the cross-linking agent and the accelerator for less than 30 seconds, forming a reversible cross linked blend, C. heating and extruding the reversible cross linked blend at a temperature less than 140 degrees Celsius for less than one minutes; and D. inserting; the reversible cross linked blend into a molding, forming a recyclable article, wherein the recyclable article comprises a resilience value up to about 50 KJ/m 2 .
