Copolymerization of ethylene with styrene, allyl benzene and 4‐phenyl‐1‐butene was examined using different metallocene catalysts. We separated the bulky phenyl group of styrene from its double bond using methylene spacers and studied the effect on its copolymerization behaviour with ethylene. The extent of incorporation of the comonomer is in the order 4‐phenyl‐1‐butene > allyl benzene > styrene for all catalysts. The comonomer incorporation was found to be less than 10 mol% under the experimental conditions employed in the present study. © 2001 Society of Chemical Industry
