A process for preparation of expandable styrene polymers, an aqueous suspension suitable therefor, expandable polystyrene produced thereby, and an article produced by shaping the polystyrene

摘要

Enhanced conversion rates are realized in a suspension polymerization process for styrene through the use of peroxide initiators having one hour half life temperatures from 101° to 111° C. are disclosed. Also disclosed are suitable initiator combinations which provide polymeric products with low residual monomer content at reduced process temperatures, polymerizable compositions containing such initiators and products produced by such processes and compositions.
