Abstract
The shelf life of polyurethane polyol pre-blends containing halogenated olefins is extended by encapsulation of active components such as catalysts and/or surfactants. The active component is encapsulated in a crystallizable or thermoplastic polymer. The encapsulated particles have a size of 2,800 microns or less and the active components are not significantly leaked out, particularly in the presence of halogenated olefins.
