  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.
