1. A method of making an aromatic polyester polyether polyurethane composition comprising:
providing a polyol component comprising:
a) an aromatic polyester polyether polyol having a structure that is either:
i) based on a glycerol backbone, the structure represented by a formula:

OG Complex Work Unit Chemistry
wherein each of R1, R2, and R3 is independently selected from hydroxyl and a structure represented by a formula:

OG Complex Work Unit Chemistry
provided that at least one of R1, R2, and R3 is not hydroxyl;
wherein m has a value such that the aromatic polyester polyether polyol has a Brookfield Cone and Plate Viscosity of less than about 5 Poise carried out using Spindle #4 at 100 rpm and 60° C.;
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, n2, and n3 is 1 to 9;
or
ii) based on a trimethylolpropane backbone, the structure represented by a formula:

OG Complex Work Unit Chemistry
wherein each of R1, R2, and R3 is independently selected from hydroxyl and a structure represented by a formula:

OG Complex Work Unit Chemistry
provided that at least one of R1, R2, and R3 is not hydroxyl;
wherein m has a value such that the aromatic polyester polyether polyol has a Brookfield Cone and Plate Viscosity of less than about 5 Poise carried out using Spindle #4 at 100 rpm and 60° C.;
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, n2, and n3 is 1 to 9; and
providing b) an isocyanate component;
mixing the polyol component and the isocyanate component to create a mixture; and
curing the mixture under reaction conditions to generate an aromatic polyester polyether polyurethane composition.
