“…There is another polyurethane acrylate formation mechanism, that of producing polyurethane pre-polymers with terminal isocyanate groups, that further react with diamine to form one component type polyurethane urea pre-polymers and these are end-capped with acrylic acid which forms curable urethane urea acrylate polymers [20,21].…”

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.

“…Unsaturated polyurethanes (uPUR), containing double bonds from polyesters soft segments [1][2][3], chain extenders [4,5] or pendant groups [6][7][8][9][10][11][12], belong to a new class of elastomers. Their importance in macromolecular chemistry follows from their possible applicability in syntheses of cross-linked polymers.…”

“…Oprea et al [7,8] have described two representations of this group, namely poly(urethane-urea-acrylates) (PUUA) and poly(urethane-ureamethacrylates) (PUUMA). These polymers were prepared in the polymerization process of isocyanate terminated prepolymers with the hexamethylenediamine and the acrylic or methacrylic acid.…”

Abstract:The cross-linked poly(esterurethanes) (PEU) based on unsaturated oligo(alkyleneester)diol (OAE) are presented. OAE was prepared from adipic acid, maleic anhydride and ethylene glycol and then characterized by elemental analysis, FTIR, 1 H NMR and 13 C NMR spectroscopy in account of double bonds and -COOH end groups. The synthesis of PEU was conducted in two steps. In the first step the prepolymers, containing free NCO or OH groups, were obtained via the reaction of OAE with 4,4`-diphenylmethane diisocyanate (MDI) used in excess. The cross-linking was achieved in the next step, in which the prepolymers were dissolved in methyl methacrylate (MMA) of concentrations in the range of 30 to 50 wt% in the presence of 1 wt% of methyl ethyl peroxide and 0.003 wt% of cobalt (II) 2-ethylhexanoate. It is proved that both chemical structure and MDI content in prepolymer influence the static and dynamic mechanical properties and thermal stability of the poly(esterurethanes).
