Photoinduced Ring‐Opening Metathesis Polymerization (PROMP) with Photochemically Generated Schrock‐Type Catalysts

Abstract

A new type of photopolymerization (depicted on the right) relies on well-defined, early transition metal complexes. Schrock-type catalysts are photochemically generated from di- or trialkyl tungsten complexes. The photoactivity and latency of the new catalysts are demonstrated by photo-differential scanning calorimetric and viscosimetric measurements.
