Title:
USE OF ARYLGUANIDINIUM XANTHATE AS VULCANIZATION ACCELERATOR, AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP2000136250
Kind Code:
A
Abstract:
To obtain a vulcanization accelerator usable without accompanying the risk of generating nitrosamine in the vulcanization of the rubber at all by including an arylguanidinium xanthate.
This vulcanization accelerator contains an arylguanidinium xanthate of formula I (R1 to R3 are each an aryl residue or H; n is 1-6, or when Y represents a monomer unit of a polymer, n is 2-20,000; Y is a hydrocarbon residue derived from a monohydric or polyhydric alcohol, or the like). The compound of formula I is preferably obtained by reacting an arylguanidinium salt (II) of formula II (A is Cl, SO4, PO4 or acetate; m is 1-3) with a salt of xanthogenic acid of formula III (B is an alkali metal or an alkaline earth metal; m is 1 or 2; x is n/m).
