摘要：The invention relates to a method for producing a polyurethane molded body,wherein (a) polyisocyanates (a-1) or polyisocyanate prepolymers, obtainable from apolyisocyanate component (a-1), polyol (a-2) containing alkylene oxide, and chain
extenders (a-3), and (b) polyether polyols containing propylene oxide and ethylene oxidewith an ethylene oxide content of 0.5 to 60 wt% and a content of primary OH groups of 1to 45%, or (c) polymer polyether polyols based on polyether polyols containing
propylene oxide and ethylene oxide with an ethylene oxide content of 0.5 to 60 wt% anda content of primary OH groups of 1 to 45%, wherein at least one of the components (b)or (c) or both components (b) and (c) are contained, and (d) chain extenders, (e) catalysts,(f) blowing agents, containing water, and optionally (g) other auxiliary agents and/oradditives are mixed to form a reaction mixture and are cured in a mold to form thepolyurethane molded body.
