Solubilization of polymer solids containing urea, isocyanurate, allophanate and/or urethane structures for use in cleaning reactor is carried out with organic solvent(s)

摘要

Process for solubilization of polymer solids (I) containing urea, isocyanurate, allophanate and/or urethane structures uses organic solvent (mixture) (II). An independent claim is included for a process for cleaning a reactor by solubilizing (I) with (II).
