Post-modification of organoiron poly(alkynyl methacrylate)s with dicobalt hexacarbonyl

Radical polymerization of organoiron (alkynyl methacrylate)s afforded a series of organoiron poly(alkynyl methacrylate)s with the ability to coordinate dicobalt hexacarbonyl. The polymers were post-modified with dicobalt hexacarbonyl moieties through reaction with dicobaltoctacarbonyl. Gel permeation chromatography indicated that the polymers possessed weight average molecular weights between 17 800 Da and 33 900 Da with PDIs between 1.3 and 1.6. Thermal analysis revealed that the polymers possess glass transition temperatures between 78 and 138 °C.
