and Summary Methyl esters of cyclopropene acids, malvalic and sterculic, and their dihydro derivatives, were highly purified and examined for melting points, poly‐morphic behavior, heats of fusion, and dilatometric behavior. Results revealed that the quickly chilled forms of the unsaturated methyl esters underwent a rapid monotropic transformation. The dihydro derivatives exhibited no detectable polymorphism. The melting dilation for methyl malvalate was signifi‐cantly below the previously reported dilations of other fatty acid methyl esters.
