| Abstract: | The effects of molecular weight, particle diameter and cooling condition on the formation of multi-hollow structure formed
within submicron-sized styrene-methacrylic acid copolymer particles by the “alkali/cooling method” proposed by the authors
were examined and the formation mechanism was proposed. The original particles were produced by emulsion copolymerization
in the presence of n-octyl mercaptan as a chain transfer agent.
