The present invention relates to a hydrophobically modified alkylene oxide urethane polymer comprising structural units of a polyalkylene glycol, an alkoxylated polyol having 50 to 250 repeating alkylene oxide units, an aliphatic diisocyanate, and a capping agent, and a process for preparing the polymer. The composition of the present invention is useful as a rheology modifier for coating compositions.

Provided are monodisperse synthetic dendrimer calibrants for mass spectrometry. The calibrants are distinguished by their relative ease and rapidity of synthesis, comparatively low cost, long shelf life, high purity, and amenability to batch synthesis as mixtures. The latter characteristic enables parallel preparation of higher molecular weight compounds displaying useful distributions of discrete molecular weights, thereby providing multi-point mass spectrometry calibration standards. Methods of making and using said calibrants are also provided.
