Abstract: Disclosed herein are methods for synthesizing oligomer mixtures with one or more moieties capable of forming a multi-hydrogen bonding dimer. The method comprises the steps of providing certain intermediate reaction products; adding a polyol component to the intermediate reaction product to yield an oligomer mixture comprising one or more multi-hydrogen bonding groups; and further reacting the mixture with certain isocyanate-reactive compounds to yield a multi-hydrogen bonding oligomer, wherein solvents comprise less than 50% of the total by weight of all reagents used in the synthesis of the multi-hydrogen bonding oligomer. Preferably, such methods involve no separation, distillation, or isolation of any intermediate product, and as such, they are particularly useful for a continuous or one-pot synthesis.

Abstract: Disclosed herein are self-healing oligomers according to the structure [UPy – (Dm – U –Dm)(2+q)] – [A(G)(n-1) – Dm]k – Z; wherein UPy, D, m, U, q, A, G, n, k, and Z are defined and described further herein, and wherein the oligomer possesses at least 3 urethane linking groups and comprises a backbone derived from a polyether polyol, a polyester polyol, a poly(dimethylsiloxane), a disulfide polyol, or combinations thereof. Also described and claimed are various compositions containing such oligomers as part of a self-healing component, wherein such compositions also include an optional reactive monomer and/or oligomer component and a photoinitiator component. Yet further described and claimed are articles cured from the compositions elsewhere described using the oligomers elsewhere described.
