CETYLTRIMETHYLAMMONIUM MALEATE

CETYLTRIMETHYLAMMONIUM MALEATE AND SULPHENAMIDE AS AN ACCELERATOR IN CARBON BLACK FILLED NATURAL RUBBER COMPOUNDS... [Pg.54]

The effects of using cetyltrimethylammonium maleate(CTMAM) and N-cyclohexyl-2-benzothiazole-2-sulphenamide(CBS) as accelerators in carbon black-filled NR compounds were studied. The results obtained showed that cure time and scorch time were faster for CTMAM... [Pg.54]

Breslow also noted that the presence of detergents such as sodium dodecyl-sulfate and cetyltrimethylammonium bromide (data not shown) had little effect on the product ratios of these aqueous Diels-Alder reactions. These results suggest that the increased endo/exo ratios and rates measured for a series of similar Diels-Alder reactions in aqueous detergent solutions by Sauer and co-workers may not be due to micellar effects as proposed [41]. Further support for Breslow s hydrophobic solvent effect hypothesis came from a study of Diels-Alder reactions of cyclopentadiene and a series of maleate and fumarate derivatives by Schneider and Sangwan [42]. They found a better correlation between the endo/exo product ratios for these reactions and solvophobicity parameters for various solvent systems as opposed to polarity effects alone. Subsequently, Cativiela et al. noted that a dual model (solvophobicity and polarity effects) can satisfactorily account... [Pg.17]
