Abstract:

The condition of oligo-micelle formation of sodium di-isodecyl sulfosuccinate (SDIDS) emulsifier in hydroalcoholicsolutions is used to study particle formation of vinyl chloride emulsion polymerization in a batch reactor.The change on micellization behavior was investigated by critical micelle concentration (CMC) and zeta potentialparameters. To detect the occurrence of secondary nucleation or particle aggregation, or both the particle size andnumber of particles were investigated as a criterion for the particle nucleation and growth process. The results showedthat the alcohol (co-solvent) content had a strong effect on the oligo-micelles formation and emulsion polymerizationperformance. Namely, decreasing the alcohol content and increasing the anion content in the SDIDS samples increasedthe overall reaction rate and latex stability. This also decreased the chain growth rate, the particle size, and the coarseparticle formation. Also, the results showed that different condition of oligo-micelle formation would lead to differentparticle growth history. Polyolefins J (2020) 7: 33-44
