This document discusses the morphology of polybutadiene thermoplastic polyurethane (TPU) and blends with polypropylene. It introduces polybutadiene-based TPUs and covers their solubility index and acid/base resistance. The document also examines the surface morphology of 50/50 blends of polypropylene and TPU under transmission electron microscopy and atomic force microscopy. Finally, it provides information about Cray Valley HSC, the global supplier of hydrocarbon resins and specialty chemicals discussed in the document.
