PROCESS FOR THE PREPARATION OF POLYETHERAL COCOOLS |
| abstract |
The invention relates to a process for the preparation of polyether alcohols by using customary H-functional starter substances and additional initiators for use in polyurethane chemistry. The invention has for its object to develop a process for the preparation of polyether alcohols by alkoxylation of H-functional starter substances and additional initiators while avoiding undesirable side reactions and optimal polyether alcohol key figures. According to the invention, the object is achieved by using H-functional cracking substances from polyurethane wastes as additional initiators and adding these polyurethane wastes before, during and / or after the alkylene oxide addition or during and / or after the cleaning the polyurethane waste either unprepared and / or mechanically comminuted or possibly activated by separate prior treatment and optionally decomposed by separation into individual H-functional components used. |
