摘要:
The present invention relates to the production of polyurethane resins and foams from stable dispersions of ionic polyisocyanate-polyaddition products in a hydroxyl containing compound as dispersing agent which are formed by the process which comprises reacting:(1) organic polyisocyanate with(2) compounds having primary and/or secondary amino grops and/or primary hydroxyl groups in(3) compounds having at least one hydroxyl group,With the proviso that compounds (3) have secondary hydroxyl groups if compounds with primary hydroxyl groups are used as compound (2), and further characterized in that at least one of the components (1) or (2) has groups which are ionic and/or capable of salt formation.
