## Abstract We report herein that 2β(perfluorooctyl)ethylacrylate (PFEA) was successfully grafted onto a segmented polyurethaneurea (SPUU). We found that certain PFEA orientated onto the grafted SPUU film surface could significantly improve hemocompatibility. 1,2βPropanediamine (PD) as a chain exte

The relationships of the morphology and properties of a series of segmented polyurethaneurea ( P U U ) were studied in film form by using SEM and tensile stress-strain data. The polyether-based and polyester-based PUU block copolymers were synthesized using poly (propylene oxide )-ethylene oxide pol
Elastic properties of segmented polyurethaneureas (SPUs) under pure shear deformation were investigated. Data were analyzed by using strain energy density function (W). The values of the derivatives of W with respect to the invariants of the strain tensor (Ii; i = 1, 2, 3) at zero strain limit were
## Abstract Linearly segmented polyurethanes and polyurethaneureas are known to be phase separated; one phase is the soft phase, the other, the hard domain. Quantitative evaluation of the degree of phase separation was obtained by DSC. An estimation of the dispersed soft segments outside the soft p
