PURPOSE: To prepare the title composition having improved adhesivity to metals, by compounding a sulfur-containing rubber with a specific surface active agent, thereby coagulating and stabilizing the super-saturated sulfur in the composition. n CONSTITUTION: A composition composed of (I) a rubber composition containing (A) 100 parts by weight of rubber selected from a natural rubber, a synthetic rubber and their blended product, and (B) 0.5W10 parts of sulfur as a vulcanizing agent, and (II) 0.1W10 wt%, pref. 0.5W5 wt%, based on the sulfur, of a surface active agent having relatively low lipophilic nature, containing an S-containing liphophilic group, and capable of coagulating and stabilizing the supersaturated sulfur in the composition, e.g. alkylxantate salt, dialkyl dithiophosphate, diphenylthiourea, etc. n COPYRIGHT: (C)1979,JPO&Japio |
