摘要

the object of the invention is a closed cellu00e1ju00fa polymer foam production process, during which a duzzadu00e1sra can monovinilidu00e9n aromu00e1spolimerku00e9szu00edtmu00e9nyt,which contains (a) a specific case, gumivaleru0151su00edtett monovinilidu00e9n aromatic polymerwith a molecular weight of at least 100 000 szerintiu00e1tlagos mass; and (c) 1-30 mass% of a high molecular weight or in limonu00e9npolimert? methyl styrene polymerthe weight average molecular weight of the 1000u201370 000,and melynekillu00e9konyanyag content of not more than 30% by weight of at least 25 degrees c warming up and u00fcvegesedu00e9sihu0151mu00e9rsu00e9klete polimerolvadu00e9k; production; the polimerolvadu00e9khoz perfectly clean foaming active substance mixrnek and a fluid mixture are prepared; the mixture under pressure melegu00edtikolyan temperatureat which the plastic mixture is not habosodik; eztku00f6vetu0151en plastic mixture under reduced pressure to habosu00edtju00e1khabszerkezet.furthermore, the invention concerns the combination of elju00e1ru00e1ssalelu0151u00e1llu00edtott plastic and foam. a
