    摘要: A process for producing reclaimed rubber has the steps of: mixing waste vulcanized rubber with unvulcanized new rubber and a devulcanizing agent; and kneading the resulting mixture in a heating atmosphere for mastication of the unvulcanized new rubber and simultaneously reclamation of the waste vulcanized rubber. Furthermore, the obtained unvulcanized reclaimed rubber can be vulcanized with a vulcanizing agent.

    摘要: The invention is to provide elastomer-like or rubber-like, recyclable cross-linked polymers capable of being liquefied and re-molded repeatedly without detracting from the physical properties of the polymers. The polymer comprises meltable cross-linked oligomer units and linkage units via which the oligomer units are linked to construct the main chains of the polymer. Each linkage unit in the polymer comprises a chemical bond that can be cleaved and re-formed repeatedly by predetermined treatment by which the bond between monomers in the oligomer units are not cleaved. The method for producing the polymer comprises a step of forming oligomer units by polymerizing monomers, a step of forming linkage units by linking the oligomer units via linkage units and a step of forming cross-linked units between the oligomer units.
