The composition of low-Tg n-butylacrylate-block-(acetoxyaceto)ethyl acrylate block polymers is investigated as a strategy to tune the properties dynamically cross-linked vinylogous urethane vitrimers. As proportion cross-linkable increased, thermorheological properties, structure, and stress relaxation evolve in ways that cannot be explained by increasing cross-link density alone. Evidence pres...
This review describes the present state of science and technology of photopolymerizable (UV-curable) polyurethane (PU) nanocomposites which include nanosilica and organically-modified clay (organoclay). A number of documented improvements of properties of PU nanocomposites compared to the pristine PU are presented. Many data on the structure and properties of PU nanocomposites were obtained not...
