Influences of styrene conversion and peroxide initiator concentration on K are studied for two different PBs. It is shown that K varies linearly with conversion, exhibits a logarithmic behaviour according to the peroxide initiator concentration, and is influenced by the microstructure of PB. Nevertheless, these effects are weak. For any peroxide initiator family studied, i.e., percarbonate, perester, and perdiketal, the values of K are close to 1, showing that peroxide initiators are evenly distributed between the PS and PB phases, before the phase inversion. © 2013 by Walter de Gruyter GmbH & Co.
