| Arkema has developed a controlled radical polymerization (CRP) technology that facilitates production of highly controlled architecture materials, such as block copolymers, using standard free radical techniques. Arkema's CRP technology is rooted in nitroxide-mediated polymerization and derived from a unimolecular initiator molecule trademarked BlocBuilderŪ; an alkoxyamine linking the initiating species and nitroxide into one molecule. BlocBuilderŪ controller controls the polymerization of a broad selection of monomer types (styrenic, acrylic, and methacrylic) in a variety of processes with only innocuous nitroxide by-products. Arkema's CRP technology provides a straightforward, robust method for the design of novel materials spanning rich architectures (block copolymers, gradient copolymers, functionalized macromonomers, graft and star copolymers, etc.) and with tailored end-use application properties simply through careful selection of polymer composition, architecture, molecular weight, and functionality. This presentation will highlight the synthetic methodologies employed using BlocBuilderŪ controller to produce commercially relevant materials with varied polymer architectures and their potential applications. |
