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 15):
The aromatic polyester polyether polyol composition of  claim 7 , wherein at least some of the composition comprises a material having one of a structure that is either:\n a. based on a glycerol backbone, the structure represented by a formula: wherein each of R 1 , R 2 , and R 3  is independently selected from hydroxyl and a structure represented by a formula: wherein m has a value such that: (i) the aromatic polyester polyether polyol has a first Brookfield Cone and Plate Viscosity of about 2.7 to about 3.2 Poise (spindle #4, 60\u00b0 C., 100 rpm); or (ii) the aromatic polyester polyether polyol has a second Brookfield Cone and Plate Viscosity of about 3.2 to about 3.8 Poise (spindle #4, 60\u00b0 C., 100 rpm); and wherein each of n 1 , n 2 , and n 3  is an integer independently selected from 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, provided that a sum of the values for n 1 , n 2 , and n 3  is 1 to 9; or b. based on a trimethylolpropane backbone, the structure represented by a formula: wherein each of R 1 , R 2 , and R 3  is independently selected from hydroxyl and a structure represented by a formula: wherein m has a value such that: (i) the aromatic polyester polyether polyol has a first Brookfield Cone and Plate Viscosity of about 3.7 to about 4.2 Poise (spindle #4, 60\u00b0 C., 100 rpm); or (ii) the aromatic polyester polyether polyol has a first Brookfield Cone and Plate Viscosity of about 4.0 to about 5.0 Poise (spindle #4, 60\u00b0 C., 100 rpm); and wherein each of n1, n2, and n3 is an integer independently selected from 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, provided that a sum of the values for n1, n 2 , and n 3  is 1 to 9.
