Benzothiazole sulfenamide

Af,Af-dicyclohexyl-benzothiazole-sulfenamide (DCBS), cobalt naphthenate, and diaryl-p-diphenylene-amine (each 1 phr). [Pg.256]

After reaction for 15 min, the band near 3295 cm (not shown in Fig. 13) decreased significantly in intensity, indicating that the mono-substituted acetylene groups were reacting. New bands also appeared near 1539 and 1512 cm . After reaction for 30 min, several additional bands appeared near 1011, 1030, 1085, 1232, 1320, 1430, and 1515 cm. The bands near 1011, 1030, 1085, 1232, 1320, and 1430 cm were clearly related to the benzothiazole sulfenamide fragment of DCBS while the band near 1539 cm was related to zinc stearate. [Pg.256]

The reaction with sulfides occurs efficiently only when the resulting carbon-centered radicals are further stabilized by a a-heteroatom. Indeed, (TMSfsSiH can induce the efficient radical chain monoreduction of 1,3-dithiolane, 1,3-dithiane, 1,3-oxathiolane, 1,3-oxathiolanone, and 1,3-thiazolidine derivatives. Three examples are outlined in Reaction (12). The reaction of benzothiazole sulfenamide with (TMS)3SiH, initiated by the decomposition of AIBN at 76 °C, is an efficient chain process producing the corresponding dialkylamine quantitatively. However, the mechanism of this chain reaction is complex as it is also an example of a degenerate-branched chain process. [Pg.127]

The chemical microstructures of cis-polyisoprene (HR) vulcanised with sulfur and N-t-butyl-2-benzothiazole sulfenamide (TBBS) accelerator were studied as a function of extent of cure and accelerator to sulfur ratio in the formulations by solid-state 13C NMR spectroscopy at 75.5 MHz [29]. Conventional (TBBS/Sulfur=0.75/2.38), semi-efficient (SEV=1.50/1.50) and efficient (EV=3.00/1.08) vulcanisation formulations were prepared, which were cured to different cure states according to the magnitude of increase in rheometer torque. The order and types of the sulfurisation products formed are constant in all the formulation systems with different accelerator to sulfur ratios. However, the amount of sulfurisation has been found to vary directly with the concentration of elemental sulfur. [Pg.330]

Figure 12.5a shows the effect of filler loading on the volume resistivity of MWNTs and CB (CB Ensaco 250G from Timcal) filled composites based on insulating styrene-butadiene rubber. The styrene-butadiene rubber contains 25 w% of styrene units. The microstructure of the butadiene phase is the following 10% cis, 17% trans, 73% 1,2. It was compounded with sulfur (1.1 phr), cyclohexyl benzothiazole sulfenamide (1.3 phr), diphenyl guanidine (1.45 phr), stearic acid (1.1 phr), zinc oxide (1.82 phr) (phr = parts per hundred parts of rubber). The unfilled and filled samples are cured into films (around 200 pm thick) at 170°C during 10 min under a pressure of 150 bar in a standard hot press. [Pg.351]

Sulfenamides, made from 170, by reactions involving primary and secondary amines under oxidizing conditions, include A-cyclohexyl-2-benzothiazole sulfenamide (173) and N-oxydiethylene-2-bcnzolhiazolc sulfenamide (2-(morpholinothio)benzothiazole) (174). Sulfenamides release 2-mercapto accelerators and amine during vulcanization. The amine is a secondary accelerator that brings about fast vulcanization after a slow start. Applications include in tyres and conveyor belts. They are not applicable to hot-air vulcanization processes95. [Pg.768]

Accelerators used include hexamine, diphenyl guanidine, ethylidene aniline, mercapto-benzothiazole, dibenzothiazole disulfide, N-Cyclohexyl benzothiazole sulfenamide, sodium diethyl dithiocarbamate, tetramethylthiuram disulfide, tetraethyl thiuram disulfide, dipentamethylene thiuram tetrasulfide, sodium isopropyl xanthate, zinc butyl,... [Pg.49]
