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

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...

Zusammenfassung: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.
