Abstract
Official abstract text for this publication.
A vulcanizing agent is added during the processing of a polymer, and can form a crosslinking structure network in the polymer, thereby improving the mechanical properties of the material. Furthermore, the crosslinking agent can also de-crosslink the polymer material at a high temperature, and after being cooled, same can be crosslinked again to produce a network structure, thus endowing the polymer material with thermoplasticity for repeated processing.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vulcanizing agent, comprising a compound selected from 2. A method for vulcanizing a polymer, comprising forming a mixture comprising a polymer, an initiator, a heat stabilizer, and the vulcanizing agent of claim 1 ; and heating the mixture to form a vulcanized polymer. 3. A method according to claim 2 , wherein a mass ratio of the polymer to the vulcanizing agent is 100:0.01 to 100:10, a mass ratio of the polymer to the initiator is 100:0.01 to 100:1, and a mass ratio of the polymer to the heat stabilizer is 100:0 to 100:1. 4. The method according to claim 3 , wherein the polymer is selected from at least one of polyolefin resins and polyolefin rubbers. 5. The method according to claim 3 , wherein the initiator is selected from organic peroxides and azo initiators. 6. The method according to claim 3 , wherein the heat stabilizer is selected from at least one of hindered phenolic macromolecular antioxidants, phosphite antioxidants, and alkyl ester antioxidants. 7. The method according to claim 3 , further comprising: feeding the mixture into a reactive processing equipment to react at a temperature above 120° C.; and extruding the heated mixture from the reactive processing equipment to form a product; and cooling the product to allow crosslinking within the product. 8. The method according to claim 7 , wherein the reactive processing equipment is single-screw extruder, twin-screw extruder, open mill, or internal mixer.
