Abstract

The oil‐in‐water (o/w) microemulsion polymerizations butyl acrylate initiated with a watersoluble (ammonium peroxodisulfate, AP) and/or and oil‐soluble (dibenzoyl peroxide, DBP) radical initiator at different monomer feed compositions and monomer concentrations were investigated. The rate of polymerization shows nucleation and termination intervals. The rate of polymerization is found to increase with the BA concentration. The polymerization is faster with AP than with DBP. The average number of radicals per particle increases exponentially with both the monomer concentration and the particle size. The number of particles decreases with monomer concentration. The molecular weights parallel the rate of polymerization and are larger in the systems with DBP.

Butyl acrylate was initiated with KPS or BPO to polymerize at high monomer concentration in the microemulsions with SBOA (sodium 12-butinoyloxy-9-octadecenate) as emulsifier. The microemulsion remained clear or reddish. It was found that the constant polymerization period appeared in most microemuls
