parallel, forming double anti-parallel chains of intermolecular hydrogenbonds using two pairs of >NH and >CO groups. In case of C6 and C7, gelator molecules were stacked through a single chain of intermolecular hydrogenbonds using a pair of >NH and >CO groups. The remaining pair of >NH and >CO groups formed an intramolecular hydrogen bond.
A method for preparing a polymeric composition, the method comprising providing a polymer cement including a polymer and a solvent; introducing a cold-flow inhibitor with the polymer cement, where the cold-flow inhibitor is selected from the group consisting of vicinal diamides, vicinal diureas and vicinal amide-ureas; and isolating at least a portion of the polymer and the cold-flow inhibitor from the solvent to provide a polymeric composition including the polymer and the cold-flow inhibitor.
