The present invention provides polymeric photoinitiators being co-polymers of photoinitiator monomers and at least one further monomer, as well as photoinitiator monomers being intermediates in the preparation of such polymeric photoinitiators. Additionally, there is provided polyacrylate obtained by radical polymerization of at least one acrylate monomer (Ac) in the presence of such polymeric photoinitiators. In the photoinitiator monomers and polymeric photoinitiators, a photoinitiator moiety, a hydrolytic stable linker and two polymerisable functional groups are incorporated into the photoinitiator structure.
本发明提供了聚合物光引发剂,其为光引发剂单体与至少一种进一步单体的共聚物,以及作为这种聚合物光引发剂制备过程中的中间体的光引发剂单体。此外,还提供了通过在存在这种聚合物光引发剂的情况下,通过至少一种丙烯酸酯单体(Ac)的自由基聚合得到的聚丙烯酸酯。在光引发剂单体和聚合物光引发剂中,光引发剂基团、水解稳定连接物和两个可聚合功能基团被结合到光引发剂结构中。
