Process development of water-based polyurethane with acrylate terminal group under water vapor permeability and water repellency for nylon fabric

Abstract: This study synthesized water-based polyurethane with acrylate terminal group (WPUA) using the long carbon chain of stearyl acrylate to synthesize hydrophobic poly-stearyl acrylate (PSA). The proposed process could minimize environmental pollution caused by fluorine-containing monomers. As a water-based polyurethane (WPU) end-capping agent, the hydrophobic PSA and the hydrophilic and water vapor permeable WPU are copolymerized to form a WPUA functional resin with simultaneous water vapor permeability (WVP) and … Show more

“…18 In relationship with chain entanglement, which requires the polymer to reach above a certain molecular weight and enables stronger hydrogen bonds, 19,20 the molecular weight of WPU is usually lower than that of solvent-based PU since its chain extension process is initiated after the formation of emulsions, leading to low chain extension efficiencies. 21 These key physical properties of WPU are highly dependent on the microscopic micellar structures of WPU, which are determined by (1) the reaction between isocyanate and polyol/amine and the competing reaction between isocyanate and water during WPU synthesis and (2) micellar coagulation during film formation. The synthesis process determines the molecular weight, as well as the resulting physical properties of WPU.…”

“…This study team proposed a novel method of using the steryl acrylate long carbochain poly-stearyl acrylate (PSA) polymer in the length of 17 carbochains as the blocking agent of WPU. 14 Moreover, hydrophilic polyol is designed as the WPU of the soft segment to give the WVP of polymer, so that the WPUA polymer derived from copolymerization has water repellency and WVP simultaneously. The proposed method can thus minimize fluorochemicals discharged into the environment.…”
