Abstract

A polymer obtainable by free-radical polymerization of one or more oxetane-based macromonomers and optionally one or more further, free-radically polymerizable comonomers, the oxetane-based macromonomer(s) being obtainable by cationic ring-opening polymerization of at least one hydroxyoxetane with a terminally ethylenically unsaturated starter molecule free of allyl groups in a molar ratio (hydroxyoxetane(s):starter molecule) of (100:1) to (1:1) in the presence of at least one suitable catalyst. Processes for preparing the polymer and the use thereof as an additive in coating compositions and plastics.
