  • Routes to polyacrylates
    Patent number: 9708425
    Abstract: A polyacrylate is obtained by radical polymerization of at least one acrylate monomer (Ac) in the presence of a polymeric photoinitiator. The polymeric photoinitiator is a co-polymer of at least one photoinitiator monomer (A) with at least one monomer (B), and optional additional monomers (C). Rapid polymerization of the acrylate monomer is provided. A method produces a polyacrylate using the polymeric photoinitiator as described, and a polymeric photoinitiator is used as the photoinitiator of radical polymerization of acrylate monomers.
