Abstract: This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure. The disclosure provides aromatic polyester polyether polyols and compositions comprising such polyols. The disclosed aromatic polyester polyether polyols and compositions including same are the products of the transesterification reaction of polyethylene terephthalate (“PET”) and an ethoxylated triol, namely glycerin or trimethylolpropane, wherein the degree of ethoxylation is from 1 to 9 moles. At least some of the PET used to generate the aromatic polyester polyether polyols is derived from recycled PET. The disclosed aromatic polyester polyether polyols have utility in preparing polyurethane materials, for example.

Abstract: The disclosure relates to methods of making foams comprising aromatic polyester polyether polyol materials derived from the transesterification of polyethylene terephthalate with either glycerin or trimethylolpropane, wherein each of these triols, independently, has a degree of ethoxylation of from 1 to 9. Uses of the foams are further disclosed. The disclosure further relates to selection of blowing agents suitable to generate a selected end use case. Yet further, the disclosure relates to selection of end uses, properties, and environmental profiles of the foams generated according to the methods herein, and selecting formulation variables suitable to obtain the foams.

Abstract: The present disclosure relates to laminate composite panels comprising a first layer of fiberglass reinforced polyester (“FRP”) and a second layer of a polyurethane material. The polyurethane layer can comprise a reaction product between an aromatic polyester polyether polyol and a diisocyanate. The polyurethane is cured-in-place on a surface of the FRP, thus creating a laminate composite material wherein the layers are adhered together without application of a separate adhesive layer. The panels exhibit improved water resistance and strength properties. The laminate composite can be adhered to a second material such as wood, polystyrene, polyurethane, or non-wovens. Such panels are particularly suitable for use in recreational vehicles, motor homes, trailers, and as building materials. Methods of making such laminate composite materials are also provided.
