    • The present invention relates to a polyether carbonate polyol made by copolymerizing a starter molecule with carbon dioxide, at a pressure ranging from about 10 psia to about 2,000 psia, and an alkylene oxide, at a temperature ranging from about 50° C. to about 190° C. and in the presence of from about 0.001 Wt. % to about 0.2 wt. % of a substantially non-crystalline double metal cyanide (DMC) catalyst, wherein the polyol has an incorporated carbon dioxide content of from about 1 wt. % to about 40 wt. %, wherein the ratio of cyclic carbonate by-product to total carbonate is less than about 0.3 and wherein the weight percentages are based on the weight of the polyol. The inventive polyether carbonate polyols may find use in producing polyurethane foams, elastomers, coatings, sealants and adhesives with improved properties.
    • 本发明涉及一种聚醚碳酸酯多元醇,其通过将起始分子与二氧化碳在约10psia至约2,000psia的压力和烯化氧的温度范围内共聚而制备,温度为约50℃至约190℃ 在约0.001Wt的存在下。 %至约0.2wt。 %的基本上非结晶的双金属氰化物(DMC)催化剂,其中所述多元醇具有约1wt。 %至约40wt。 %,其中环状碳酸酯副产物与总碳酸盐的比例小于约0.3,并且其中重量百分比基于多元醇的重量。 本发明的聚醚碳酸酯多元醇可用于生产具有改进性能的聚氨酯泡沫,弹性体,涂料,密封剂和粘合剂。

    • Polyols containing polyether and polyester moieties, based on phthalic acid are described. A phthalic acid derivative is reacted with a polyether polyol to give the novel polyols which are useful not only in polyisocyanurate foams, but also polyurethane foams as well. The phthalic acid derivative may be phthalic acid, phthalic anhydride and an ester of phthalic acid, for example. The polyester polyol is made from an initiator selected from the group consisting of alkanolamines, alkyleneamines, arylamines, sucrose, glycerin, sorbitol, .alpha.-methylglucoside, .beta.-methylglucoside, and mixtures thereof. The polyester polyol may be made by alkoxylating the initiators.
    • 描述了含有基于邻苯二甲酸的聚醚和聚酯部分的多元醇。 使邻苯二甲酸衍生物与聚醚多元醇反应,得到不仅可用于聚异氰脲酸酯泡沫,而且可用于聚氨酯泡沫的新型多元醇。 邻苯二甲酸衍生物可以是例如邻苯二甲酸,邻苯二甲酸酐和邻苯二甲酸的酯。 聚酯多元醇由选自链烷醇胺,亚烷基胺,芳基胺,蔗糖,甘油,山梨糖醇,α-甲基葡糖苷,β-甲基葡糖苷及其混合物的引发剂制成。 聚酯多元醇可以通过使引发剂烷氧基化来制备。
