Description

General description

4-Chlorostyrene is a para-halogenated styrene derivative. It undergoes graft copolymerization with acrylonitrile (AN) onto ethylene-propylene-diene terpolymer (EPDM) in the presence of benzoyl peroxide (initiator).

Application

4-Chlorostyrene was used in the following studies:

• Study of chemical and biochemical properties of the vinyl group of styrene by the development of structure activity relationships (SAR).
• Preparation of new bis(pyrazolyl)borato olefin complexes of copper(I).
• To investigate the regioselectivity in the cationic Heck reaction of 4-substituted styrenes.
