Abstract: The present invention provides a ring-containing component polyol and process for making the same for use as a load-bearing capacity improvement agent in flexible polyurethane foam manufacture. The ring-containing component polyol eliminates and/or reduces the need for a copolymer polyol containing suspended solids in the manufacture of flexible foam products. This may reduce production costs, reactivity variations, filter plugging, color variations, foam shrinkage/tightness, foam irregularity, and foam malodor while maintaining an adequate load-bearing capacity. The present polyol blends can be non-opaque or transparent.

Abstract: 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.

Abstract: Isocyanate-modified polyester-epoxide polymer (i-PEEP) compositions are disclosed. The i-PEEP compositions comprise a reaction product of a polyepoxide compound, a polyisocyanate, and a polyester polyol composition. The ratio of epoxy equivalents to hydroxyl equivalents is within the range of 0.2 to 2. The i-PEEP index as defined herein is within the range of 100 to 200. The i-PEEP composition has a T g within the range of -30°C to 35°C. Low- and elevated-temperature processes catalyzed by bases or Lewis acids for making the i-PEEP compositions are also disclosed. In a simple yet innovative approach, a new class of polymers useful for coatings, elastomers, adhesives, sealants, and other valuable products is assembled from readily available starting materials without reliance on the polyamines typically used to cure epoxy systems.
