Title:
VULCANIZATION ACCELERATOR AND FLUORORUBBER COMPOSITION FOR VULCANIZATION
Document Type and Number:
WIPO Patent Application WO/2002/036671
Kind Code:
A1
Abstract:
A vulcanization accelerator giving a vulcanizable fluororubber composition which can be effectively prevented from scorching during storage and in a pretreatment for vulcanization, has a high vulcanization rate in actual vulcanization to attain a reduction in vulcanization time, and has vulcanization characteristics optimal for injection molding. It comprises an onium salt in which the anion is a phenol compound, especially one represented by the formula (I) (I) (wherein A?+¿ is the cation of the onium salt; X is a functional group which enables the substituted phenol constituting the anion of the onium salt to have a pK¿a? of 3.2 to 12.4; and n is an integer of 0 to 5). Also provided is a fluororubber composition for vulcanization which comprises the vulcanization accelerator, a fluororubber vulcanizable with a polyol, and a polyol vulcanizing agent.
