“…Here, we will focus on the specifics of the solution, also termed the acetone process, since the majority of PUDs discussed in this review were synthesized accordingly. Scheme illustrates the solution process for the synthesis of a fluorescent dye‐containing PUD . In the first step, tolylene‐2,4‐diisocyanate (TDI), PPG, and 2,2‐bis(hydroxymethyl)propionic acid (DMPA) react to form an isocyanate end‐capped prepolymer containing a pendant carboxylic acid.…”

Despite the well-established foundation of polyurethane chemistry in both industry and academia, research continues at a vigorous pace to refi ne synthetic processes and discover new functional materials. Incorporating ionic groups into polymers is a synthetic parameter capable of tailoring polymer properties and enabling emerging technologies. This review focuses on recent effort in the fi eld of ion-containing segmented polyurethane copolymers. Multiple synthetic strategies to incorporate both cationic and anionic sites, including a particular focus on waterborne polyurethane dispersions and green synthetic methods, are examined. Fundamental structure-property relationships based on ionic structure, content, and placement are explored and many applications, including biomedical products and polymer electrolytes for energy devices are discussed.(PEG) or poly(tetramethylene oxide) (PTMO), to the polyurethane reaction. The hydrogen bonding, depicted in Figure 1 , between the urethane carbonyl oxygen and urethane hydrogen, coupled with crystallization, constructs the hard segment (HS) domains, while the functionalized fl exible spacers comprise the soft segments (SSs) in an alternating fashion. The microphase-separated morphology of segmented polyurethanes is the foundation for their versatility, with the ability to further tune materials for a specifi c application with other synthetic parameters such as chemical composition and molecular weight. Yilgör and co-workers, [ 5 ] Yurtsever and co-workers, [ 6 ] and Wilkes and co-workers [ 7 ] extensively studied various model segmented polyurethane systems to further understand the morphology and factors infl uencing morphology on a fundamental structure-property level.Many comprehensive reviews and peer-reviewed journal articles focus on fundamental structure-property relationships of segmented polyurethanes.

A series of sulfonated waterborne polyurethane-based dyes (DB60-SWPUs) with covalently bonded to different proportions of Disperse blue 60 (DB60) were prepared by a modified acetone process. The expected structures of DB60-SWPUs are characterized by Fourier transform infrared spectroscopy and 1 H-NMR spectra. The obtained DB60-SWPUs show high viscosity and intriguing storage stability. The fluorescent performances, thermal properties, and mechanical properties of DB60-SWPUs were characterized. Compared with DB60, the UV-vis spectra of DB60-WPUs have obvious hypochromic shift, and the fluorescence intensities are obviously enhanced. The migration rates of DB60-SWPUs are much lower than that of DB60. DB60-SWPUs have thermal migration resistance and excellent color fastness. The polyester fiber dyed by DB60-SWPUs has not only high color yield, good fracture strength, excellent breaking strength retention, but also good permeability and wrinkle resistance. Moreover, DB60-SWPUs are polymeric dyes with water as a solvent, which are especially suitable for environmental protection.

“…The fluorescence intensities of emulsions were obviously enhanced with enlarged average particle sizes. This was attributed to enlarged average particle sizes of emulsions with the increased MMA contents, which augmented the light absorption area of the ACBD segments [31][32][33][34][35].…”

A waterborne polyurethane-acrylic hybrid polymeric dye was prepared depending on soap-free emulsion polymerization method. The resulting polymeric dye composed of methyl methacrylate (MMA) monomer which was polymerized into polymethyl methacrylate (PMMA) as cores and waterborne polyurethane-based dye was synthesized by anchoring dye monomers (6-amino-2-cyclohexylbenz[de]isoquinone-1,3-dione) to polyurethane chains as shells. The average particle sizes of the hybrid polymeric dye emulsions were found to be increased with the increase in MMA contents for MMA monomers. Compared with dye monomers, the absorption intensities and fluorescence intensities of the hybrid polymeric dye were enhanced with the increase of particle sizes. This study revealed that enhanced fluorescence intensity of the hybrid polymeric dye was mainly attributed to the hindered formation of exciplexes among dye monomers and an augmented light absorption area. It was found that the fluorescence intensity of the hybrid polymeric dye was increased with increasing temperature and the trend first increased and then decreased with increase in concentration. Furthermore, the fluorescence of the hybrid polymeric dye emulsions was found to be very stable and not sensitive to the fluorescence quencher.
