Abstract: The invention describes an improved method for the preparation of rubber compounds which comprises compounding the rubber and the components at 125 - 200°C in the presence of an amount of 0.1 - 2% based on the weight of the rubber of a processing stabilizer of the formula (I) wherein R1 is hydrogen, C1-C20alkyl, styryl, α-methyl-styryl or -CH2-S-R3; or C1-C20alkyl substituted with C2-C20alkenyl, C3-C20alkinyl, C5-C9cycloalkyl, phenyl or tolyl; R2 is C1-C20alkyl or -CH2-S-R3, R3 is C1-C20alkyl; with phenyl, hydroxyl, cyano, formyl, acetyl or -O-CO-R5 substituted C1-C20alkyl; C2-C20alkenyl, C3-C20alkinyl, C5-C9cycloalkyl; or with hydroxyl, phenyl, 4-chloro-phenyl, 2-methoxycarbonylphenyl, p-tolyl, 1,3-benzthiazol-2-yl, -(CHR5)nCOOR6 or -(CHR5)nCONR7R8 substituted C5-C9cycloalkyl; R4 is hydrogen or methyl, R5 is hydrogen or C1-C6alkyl, R6 is C1-C20alkyl; with oxygen or sulfur interrupted C3-C20alkyl; C5-C9cycloalkyl, phenyl, benzyl or tolyl, R7 and R8 are independently of each other hydrogen or C1-C6alkyl, and n is 1 or 2.
