Polyester polyols and methods of making and using the same
Polyester polyols are generally disclosed, including methods of making and using them. In some embodiments, the polyester polyols are incorporated into a block copolymer, such as a polyurethane block copolymer. In some embodiments, the polyurethane block copolymers can be used as compatibilizing agents, which can be used, for example, in polymer blends, polymer alloys, solutions, emulsions, as well as in extruded and injection molded articles. In some embodiments, at least a portion of the polyurethane block copolymer is derived from a renewable source.
