摘要： An aromatic polyester polyol having a nominal functionality of at least about 2 is produced from the esterification reaction of a phthalate-based composition containing less than 50 mol% of ortho-phthalic acid or phthalic anhydride, with a hydroxyl material containing at least 20 mol% of at least one branched aliphatic diol, and optionally transesterified with at least one hydrophobic material. The polyester polyol has improved shelf-life stability as demonstrated by the polyester polyol remaining clear and homogeneous for at least 6 months when stored at room temperature. The polyester polyol, when incorporated into a polyol foam-forming resin composition in an amount of at least 40 wt %, results in polyurethane and polyisocyanurate foams that exhibit low smoke and weight loss upon burning conditions.

摘要： Polyester polyols containing adducts formed from Diels-Alder and Ene reactions are disclosed. Processes for making the polyester polyols and uses of the polyester polyols as polyurethane coatings, adhesives, sealants, elastomers, and foams are also disclosed. In some embodiments, the polyester polyols contain biorenewable adducts based on maleic anhydride and farnesene and have particular application in making rigid and flexible polyurethane or polyisocyanurate foams.
