The seeded microemulsion polymerization of butyl acrylate was studied with β₯-rays. The hydrodynamic diameter and its distribution of polymer particles in the seeded microemulsion before and after polymerization were determined with photon correlation spectroscopy (PCS). Though there were micelles in

β¦ Synopsis
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 microemulsions and the length of it varied with the concentration of monomer and the initiating rate. When microemulsions were initiated with KPS, the overall polymerization rate increased with the emulsifier concentration; while initiator was BPO, it showed the inverse tendency. It was attributed to the difference .between the initiating mechanism of the two initiators. 0 1996 John Wiley & Sons, Inc.

The anionic polymerization of tBMA initiated by an organolithium compound in toluene at low temperature (Γ78 Β°C and 0 Β°C) has been revisited. Under these experimental conditions, no `livingness' is reported, consistently with formation of an important fraction of oligomers (M n = 650).
The oil/water microemulsion polymerizations of alkyl (methyl (MA), ethyl (EA), butyl (BA), hexyl (HA) and 2-ethylhexyl (EHA)) acrylates initiated by a water-soluble (ammonium peroxodisulphate (APS)) initiator were investigated. The rate of polymerization versus conversion curve shows two inconstant
