Beschreibung
Zusammenfassung:	The present invention relates to a polyol premix composition for rigid polyurethane foams comprising a hydrohaloolefin as foaming agent, an amine catalyst and an aliphatic dicarboxylic acid. The polyol premix composition has a high initial reaction rate when it is reacted with isocyanatc and shows smaller deterioration of reactivity over time. 本发明涉及用于硬质聚氨酯泡沫塑料的多元醇预混物组合物，其包含作为发泡剂的氢卤烯烃、胺催化剂和脂族二羧酸。当所述多元醇预混物组合物与异氰酸酯反应时，其具有高初始反应速率，并且随着时间的推移表现出较小的反应性劣化。
