Reactive surfactant sodium dodecyl allyl

Chern and Chen [30] studied the effect of the reactive surfactant, sodium dodecyl allyl sulfosuccinate, on the semibatch emulsion polymerization of n-butyl acrylate initiated by sodium persulfate. Sodium dodecyl allyl sulfosuccinate plays a similar role in the particle nucleation and growth stages to the conventional sodium dodecyl sulfate. The final number of latex particles per unit volume of water is proportional to the concentration of sodium dodecyl allyl sulfosuccinate in the initial reactor charge (the most important parameter with regard to particle nucleation) to the 0.72-0.80 power. The saturated particle surface area occupied by one molecule of sodium dodecyl allyl sulfosuccinate is 0.36 nm for the poly (n-butyl acrylate) particles prepared by the... [Pg.182]

Details are given of the seeded emnlsion polymerisations of styrene using the reactive snrfactant sodium dodecyl allyl sulphosuccinate and its polymeric counterpart. Reaction kinetics were compared with those obtained using the conventional surfactant sodinm lauryl sulphate. Results were supported by molecular weight data. 18 refs. USA... [Pg.44]

Another approach to producing latexes with chemically bound surface-active groups is to use a reactive surfactant—a surfactant with a polymerizable double bond, such as sodium dodecyl allyl sulfosuccinate [Wang et al., 2001a,b,c]. Copolymerization of the reactive surfactant with the monomer of interest binds the surface active groups into the polymer chains. [Pg.367]
