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.

Claim (Index 7):
An aromatic polyester polyether polyol composition derived from transesterification of polyethylene terephthalate (\u201cPET\u201d) in the presence of an ethoxylated triol and, optionally, a catalyst, wherein the ethoxylated triol comprises one of:\n a. glycerin having from 1 to 9 moles of ethoxylation; or b. trimethylolpropane having from 1 to 9 moles of ethoxylation.
