PROCESS FOR PREVENTING PREMATURE VULCANIZATION OF RUBBER

摘要

PURPOSE:To suppress premature vulcanization of a rubber in the crosslinking of the rubber with an organic peroxide without deteriorating the physical properties of the vulcanized rubber. CONSTITUTION:Premature vulcanization in the crosslinking of a rubber with an organic peroxide is suppressed by carrying out the crosslinking in the presence of a sulfidized phenolic resin and/or sulfidized alkylphenolic resin. The amount of the sulfidized phenolic resin and/or sulfidized alkylphenolic resin is 0.1-5.0 pts.wt. (preferably 0.5-2.0 pts.wt.) based on 100 pts.wt. of the rubber.
