The photolysis product of photoinitiator and its preparation route

According to the molecular structure and the location of photosensitive groups, the existing macromolecule photoinitiator can be divided into three categories: linear polymer photoinitiator (LPPI), hyperbranched/crosslinked photoinitiator (HCPPI) and multifunctional photoinitiator (MFPI). LPPI has been widely reported because of its simple preparation method and flexible chemical structure.

There are two main routes of LPPI synthesis:

First, the polymerizable monomer with photoinitiator structure was prepared, and then the LPPI was formed by thermal polymerization.

Second, the linear polymer with active group on the side chain was prepared first, and then the photoinitiator group was grafted onto the side chain.
