摘要：
Distribution of peroxyester groups between the aqueous and organic phases in polystyrene lattices prepared in the presence of peroxide stabilizers was studied by combining the iodometric and ceriometric methods for quantitative peroxide determination. All peroxide groups are localized in the vicinity of the interface. 30 to 40% of them are oriented towards the organic phase, the remaining are oriented towards the aqueous phase and can be cleaved by hydrolytic reactions.
