4-氯苯乙烯是一种对位卤代苯乙烯衍生物。在过氧化苯甲酰（引发剂）存在下，它与丙烯腈（AN）接枝共聚到乙烯-丙烯-二烯三元共聚物（EPDM）上。 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. 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). 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.
