Abstract
This study was aimed at modifying the surface of aromatic phthalide-containing polymers, promising for use in membrane technologies, with aliphatic polymer brushes of varying polarity. Mono- and polyfunctional vinyl monomers with various side groups, including reactive ones, were used: hydroxyl, ether, ester, acid, epoxy, and nitrile. The possibility of graft copolymerization of acrylates and methacrylates, as well as some other vinyl monomers, on the surface of brominated polydiphenylenephthalide (PDP-Br) was investigated. The influence of the degree of halogenation of PDP-Br and irradiation dose and duration on the degree of grafting was studied. It has been shown that brominated PDP is a polymeric photoinitiator for a wide range of vinyl monomers, the use of which in graft copolymerization processes allows the production of grafted aromatic–aliphatic copolymers of various chemical structures with different hydrophilic/hydrophobic ratios.
期刊介绍：
Doklady Chemistry is a journal that publishes new research in chemistry and chemical engineering of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
