Application

1. Organic intermediates

4-Chloromethylstyrene is widely used in various fields of synthesis. Li Tongde et al. used phase transfer catalysis to hydrolyze 4-chloromethylstyrene to obtain p-vinylbenzyl alcohol, which is an indispensable raw material for the synthesis of new photosensitive materials and new high-efficiency flame retardants. According to US patents, 4-chloromethylstyrene can be used as a raw material to synthesize a certain herbicide that can effectively kill weed seeds. 4-Chloromethylstyrene can also be used to synthesize p-vinyl acetic acid, which is an important raw material for synthesizing plasticizers, ion exchange resins and cross-linking agents. 4-Chloromethylstyrene is also an important intermediate for the synthesis of non-steroidal anti-inflammatory analgesic drug loxoprofen.

2. Polymer graft copolymers

Polymer graft copolymers contain main chains and side chains with very different properties and have many excellent comprehensive properties. They can be used as emulsifiers, solubilizers, surfactants, phase transfer catalysts, antistatic agents and biomedical materials. Hu Chunhong et al. introduced a certain proportion of chloromethyl groups into the main chain of polystyrene by copolymerizing styrene (St) with 4-chloromethylstyrene, synthesized a macromolecular initiator with controllable relative molecular mass and chloromethylation rate, and then initiated the atom transfer radical polymerization of methyl methacrylate to synthesize graft copolymers. Zhang Yongming et al. copolymerized 4-chloromethylstyrene with other vinyl monomers to obtain a series of macromolecular initiators with -PhCH2CI side groups, and used them to initiate monomer atom transfer radical polymerization to form graft copolymers.

3. Organic silicon polymer materials

Organic silicon polymer materials have unique advantages in thermal stability, photostability, chemical stability or biological inertness. Yang Ruiqin et al. polymerized 4-chloromethylstyrene on the surface of silicon materials with double bonds, and further quaternized them to prepare a new type of strong anion chromatographic column filler. This filler has the characteristics of wide pH range of organic matrix stationary phase and good mechanical strength of silicon-based fillers.

4. Nanomaterials

Surface grafting polymer modification can significantly reduce the surface polarity of inorganic nanoparticles and improve their compatibility with the polymer matrix and dispersion stability. Wang Guojian et al. first synthesized hyperbranched poly (4-chloromethylstyrene), then converted the chlorine atoms into -N3 through azide reaction, and then grafted poly (4-chloromethylstyrene) onto the surface of carbon nanotubes through the reaction of -N3 with single-walled or double-walled carbon nanotubes, thus achieving chemical modification of carbon nanotubes. The poly (4-chloromethylstyrene) grafted nano-silica prepared by Liu Peng et al. has a large number of atom transfer radical polymerization initiating groups on the surface, which can be used as a large surface initiator for atom transfer radical polymerization to prepare comb-shaped polymer grafted inorganic nanoparticles with regular structure and controllable molecular weight.

5. Other applications

The cross-linked p-CMS-St series fibers can be used as membrane reinforcement materials, and can also be used in combination with ion exchange matrix. In the field of photography, adding polymers of 4-chloromethylstyrene amine derivative salts can save resources and reduce the amount of silver halide in photographic films; 4-chloromethylstyrene tertiary amine polymers have certain applications in liquid developers. Diphenylamine derivatives of 4-chloromethylstyrene can be used as excellent synthetic rubber anti-deterioration agents, increasing the safety of premature vulcanization by 3-9 times. After being coated on steel plates and heat-treated, sulfur derivatives of 4-chloromethylstyrene can form a hard and highly solvent-resistant film. Quaternary ammonium salts of 4-chloromethylstyrene can be used as polymer flocculants. Derivatives of 4-chloromethylstyrene can be used as organic photosensitive materials to replace inorganic selenium photosensitive materials.
