Abstract
Process for obtaining semi-hard foamed materials, from polyhydroxy compounds of molecular weight 800 to 10,000, preferably 1,000 to 05,000, crosslinking agents bearing polyisocyanates and hydroxyl groups, with a molecular weight of less than 500, water and, if appropriate, organic propulsion agents, as well as, if appropriate, in the presence of known foaming auxiliaries, characterized in that, as crosslinking agents, those aliphatic compounds are used that, in addition to at least one hydroxyl group, contain at least a group ** (see formula) ** Wherein r'is an alkyl or hydroxyalkyl radical having 1 to 12 carbon atoms and r is preferably hydrogen, a linear or branched alkyl radical having 1 to 18 carbon atoms, preferably 1 to 6 carbon atoms, a linear alkylene radical or branched with 1 to 18 carbon atoms, preferably with 1 to 6 carbon atoms, the group ** (see formula) ** (x represents an integer between 1 and 6) or (see formula) (Machine-translation by Google Translate, not legally binding)
