A method for the preparation of cellular plastics according to the polyisocyanate polyaddition process of - and low-boiling, fluorinated and / or perfluorinated, tertiary alkylamines as blowing agent here for emulsions containing

摘要

items of the invention are a process for the production of zellhaltigen plastics after the polyisocyanat - polyadditionsverfahren through implementation of $(a) organic and / or modified.ganischen polyisocyanaten with $a (b) at least one hu00f6hermolekularen connection with at least two reactive hydrogen atoms, and, where appropriate, $a (c) low molecular weight kettenverlu00e4ngerungs and / orvernetzungsmitteln $a $a (d) in the presence of teibmitteln, $a (e) catalysts, $a (f) tools and / or additives, $a and as a foaming agent (d) are used niedrigsiedende, d1) $afluorinated or perfluorinated tertiary alkylamines, $a and $b mixtures of (d1) and at least one other of (d1) differentthe physical and / or chemical formed propellant (d2) $a and treibmittelhaltigen emulsions for the above foaming (d1) or the treibmittelmischung (d1) and (d2) sowie the aufbaukomponenten (a), (b), (c) or (b) and (c).
