Synthesis and characterization of linear and crosslinked poly(urethane urea) elastomers with triazine moieties in the main chain

Amide-containing segmented copolymers

“…[insensitive rubbery plateaus typical of highly microphase-separated segmented copolymers. The range of the plateau region and storage moduli are highly dependent on copolymer composition, allowing for the tailoring of mechanical properties through structural alterations 24,26,29. Increasing polyether SS length resulted in a systematic decrease in the observed flow temperature and storage moduli of PEEA copolymers due to a decreased wt% HScomposition.…”

The Effect of High Molecular Weight Bio-based Diamine Derivative of Dimerized Fatty Acids Obtained from Vegetable Oils on the Structure, Morphology and Selected Properties of Poly(ether-urethane-urea)s

“…The second step is connected with decomposition of soft segments [28]. The presence of urea bonds in the structure of poly(urethane-urea)s can improve thermal stability in comparison to similar polyurethanes [29]. The course of the weight loss curves of tested poly(urethane-urea) s are very similar.…”

An evaluation of the mechanical and adhesion properties of a hydroxyl-terminated polybutadiene (HTPB)-based adhesive including different kinds of chain extenders

“…8,9. Figures 8,9 show that ISL and PDO chain extenders changed the storage modulus of the polyurethane at plateau rubbery region.…”

“…A wide range of polyurethane adhesives can be produced by changing the urethane content and the other building blocks presented in its formulation [2][3][4][5][6][7][8]. The building blocks of the polyurethane adhesives are mainly based on the polyisocyanates and polyols with 2-3 reacting groups per molecule.…”
