Kinetic aspects of formation and processing of polycaprolactone polyurethanes <i>in situ</i> from a blocked isocyanate

Abstract

To produce segmented polyurethanes that can be processed readily into elastomeric thin films, a thermally labile blocking agent was used to synthesize an isocyanate prepolymer. The final product was formed by bulk thermal polymerization. The resulting polymer morphology imparted enhanced mechanical properties.
