“…The reaction was continued for 30 min and there was a thick, viscous and transparent material in the reaction vessel (Wang et al, 2008) which indicates the formation of vinyl terminated PU prepolymer (Scheme 1b). The formation of the vinyl terminated prepolymer was confirmed by FT-IR (Fig.…”

“…There are only a limited number of reports about the preparation and application of eco-friendly binder for textile finishing purposes. Great efforts have been dedicated to the combination of polyurethanes with acrylic polymers to increase the performance-to-cost of the coatings (Wang, Hu, & Tu, 2008). In this way, extensive possibilities are offered to obtain the polymer structure which will be compatible for particular intention (Król et al, 2005).…”

“…[1][2][3] However, due to the substitution of long and weak intermolecular van der Waals distance by short and strong covalent bonds, 4-6 high volume shrinkage is one of major drawbacks during photopolymerization, which can lead to material failures and short service life of obtained materials.…”

Polyurethane acrylates (PUAs) modified by different amounts of stearyl alcohol were synthesized from stearyl alcohol (SA), isophorone diisocyanate, 2-hydroxyethyl acrylate, and polycaprolactone triol. The molecular structure was characterized by Fourier transform infrared spectroscopy. Real time infrared spectroscopy was used to investigate the kinetics of photopolymerization of synthesized PUAs. The volume shrinkage was measured by laser displacement sensor. The adhesion on glass, polycarbonate (PC), and polyvinyl chloride (PVC) was tested by the laser micrometer and universal testing machine. The glass transition temperature (T g ) and storage modulus (E¢) were measured by dynamic mechanical analyzer (DMA). The pendulum hardness, pencil hardness and flexibility were also measured. The results showed that the greater the amount of SA in synthesized PUAs, the lower the volume shrinkage and the better the adhesion to glass, PC, and PVC substrates.

Several UV-and heat-curable polyurethane urea amide acrylate polymers were synthesized from 4,4 -diphenyl methane diisocyanate, poly(1,2-ethane diol), poly(1,3-propane diol), poly(1,4-butane diol), 1,6-hexamethylene diamine and acrylic acid. We have investigated the effects of polyol type and of the length of methylenic chain on their properties. The increase of polyol methylenic chain led to a lower glass-transition temperature, an increasing tensile modulus and strength and increased thermal stability. These soft elastic segment structures, in addition to the physical and chemical cross-linked nature of the hard segment, provide enough cross-link sites to have an elastomeric behaviour.
