An object of the invention is to provide resin premix compositions which include a polyol and a hydrocarbon foaming agent while still exhibiting good storage stability, the polyol being obtained without the use of ring-opening polymerization reaction of a cyclic ether. The resin premix composition of the invention includes at least a polyol and a hydrocarbon foaming agent, the polyol including a polyether ester polyol (A) obtained by reacting a polyether polyol with a fatty acid and/or a fatty acid ester, the polyether polyol being obtained by condensing a polyhydric alcohol including 50 mol% or more of a trihydric or higher alcohol.
本发明的目的是提供一种
树脂预混料组合物,其中包括一种多元醇和一种烃类发泡剂,同时还具有良好的储存稳定性,这种多元醇是在不使用
环醚开环聚合反应的情况下获得的。本发明的
树脂预混料组合物至少包括一种多元醇和一种烃类发泡剂,多元醇包括一种聚醚酯多元醇 (A),该多元醇是通过聚醚多元醇与
脂肪酸和/或
脂肪酸酯反应获得的,聚醚多元醇是通过缩合含有 50 摩尔%或更多三
水或三
水以上醇的多元醇获得的。
