Abstract
En fremgangsmåte for smeltesammenblanding av polymerer omfattende å blande i to trinn en polymer med høy molekylvekt og en polymer med lav molekylvekt er beskrevet. Totrinnsprosessen utvider området for molekylvekten av polymerer som kan anvendes og området for vekt- forholdet av sammensetninger som kan blandes effektivt.
