A combinatorial approach for the synthesis of supramolecular gelators as new organic materials is described herein. In the course of the development of a convenient and flexible solid-phasesynthesis of the artificial glycolipids, some of these compounds were accidentally found to act as lowmolecular-weight gelators toward organic solvents. Using this combinatorialsolid-phasesynthesis of glycosylated
A pavement marking composition comprises an isocyanate-containing component and an amine-containing component. At least one of the components comprises plasticizer and at least one of the components comprises filler. The composition comprises about 5 wt. % or more plasticizer and is substantially free of polyaspartic ester amines.

azide‐alkyne Huisgen dipolar cycloaddition between azidized PVC and electron‐poor acetylenediamides incorporating a branched glutamic acid linker resulted in incorporation of four plasticizing moieties per attachment point on the polymer chain. A systematic study incorporating either alkyl or polyethylene glycol esters provided materials with varying degrees of plasticization, with depressed Tg values ranging
