Abstract
PURPOSE: To prepare an agent giving a vulcanized rubber having excellent compression set, by compounding powders of calcium oxide and a specific calcium salt, or their oil-treated dispersion, with a specific amount of a Ti-containing organic uni-functional coupling agent.
CONSTITUTION: Powders of calcium oxide, mixed powders of calcium oxide and calcium hydroxide, or calcium oxide and calcium carbonate, or their oil-treated dispersion, are compounded with 0.5W20% of isopropyl triisostearic titanate which is a Ti-based organic uni-functional coupling agent, and kneaded vigorously with a high-speed mixer, etc. to obtain the title agent.
