The synthesis of star‐shaped adamantane multipodes with rigid branches based on p‐hydroxybenzoic acid is reported. These multipodes are able to crystallize but can also be obtained in the glassy state. They are soluble in various low molar mass organic solvents, in fact, much better than linear rigid molecules of similar length, and they are miscible in polymer matrices up to concentrations of 30 wt%. The multipodes were found to influence the dielectric and mechanical properties of the polymers significantly.
