CURABLE COMPOSITIONS WITH MOISTURE-CURABLE FUNCTIONALITY CLUSTERS NEAR THE CHAIN ENDS

A process of controlled radical polymerization, and products made therefrom is disclosed. The process includes performing controlled radical polymerization on a composition comprising a polymerizable compound, an initiator, a ligand, and a catalyst; permitting the controlled radical polymerization reaction to proceed until a desired level of conversion is attained, but prior to complete conversion to obtain an intermediate polymerization product; and further reacting the intermediate polymerization product with a reactant having a cluster of multiple reactive sites to provide a polymer reaction product having a cluster of pendent multiple reactive sites adjacent to said terminal ends of said polymer reaction product.

Macro-photoinitiators and curable compositions thereof

Macro-photoinitiators having defined polymer chain structure are provided. The macro-photoinitiators are terminated with residues of thiol and/or hydroxyl functional photoinitiators. The macro-photoinitiators may be prepared by controlled radical polymerization methods, such as atom transfer radical polymerization and single electron transfer polymerization methods. Also provided are curable (e.g., photocurable) compositions that include the macro-photoinitiators of the present invention.
