Chlorostyrene

Chlorostyrene is a term that can refer to several different chemical compounds. Specifically, it denotes styrene molecules that have had one or more chlorine atoms substituted onto the benzene ring. The most common and industrially relevant isomer is 4-chlorostyrene, also known as p-chlorostyrene. Other isomers include 2-chlorostyrene (o-chlorostyrene) and 3-chlorostyrene (m-chlorostyrene).

These compounds are derivatives of styrene, a monomer that is widely used in the production of plastics like polystyrene. The introduction of chlorine atoms can alter the physical and chemical properties of the styrene molecule, influencing its polymerization behavior and the characteristics of the resulting polymers. For instance, chlorostyrene monomers can be polymerized or copolymerized with other monomers to create specialized polymers with properties such as increased flame retardancy or modified solubility.

4-Chlorostyrene, in particular, has found applications in the synthesis of various materials. It can be used as a comonomer in the production of certain types of synthetic rubbers and resins. The presence of chlorine can also affect the glass transition temperature and mechanical strength of polymers derived from chlorostyrene. The specific applications and production methods depend on the desired properties of the final product.
