Abstract

En fremgangsmåte for fremstilling av en styrenpolymer-skumstruktur, og som omfatter: a) et styrenpolymer-materiale omfattende mer enn 50 vekt% styren-mono- merenheter og 0,1-40 vekt% oksygenhol- dige monomer-enheter, basert på den to- tale vekt av styrenpolymer-materialet, oppvarmes under dannelse av en polymer- material-smelte; og b) et esemiddel som omfatter 5 vekt% eller mer av karbondi- oksyd, basert på den totale vekt av ese- midlet, innarbeides i polymermaterial- smelten. Videre en skumstruktur som kan oppnås ifølge ovennevnte fremgangsmåte. Innholdet av komonomerer som inneholdenr oksygen, i styrenpolymer-materialet gjør mulig at driftstrykkene for prosessen kan reduseres betydelig ved anvendelse av karbondioksyd som esemiddel, sammen- liknet med et styrenpolymer-materiale uten komonomer-innhold. Den dannede skumstruktur har lav densitet og god kvalitet.
