the polyolefin without causing branching and/or crosslinking side reactions.
Scheme 6 illustrates the general reaction scheme of a simple thermal process to
form maleic anhydride-modified polyolefin and crosslinked polyolefin.
Table 5 summarizes the experimental results of the copolymerization reaction
between ethylene and 1,4-divinylbenzene (DVB) using various metallocene
catalysts, including Cp 2 ZrCl 2 , Ind 2 ZrCl 2 , rac-Et(Ind) 2 ZrCl 2 , Me 2 Si(Ind) 2 ZrCl 2 ,
and [C 5 Me 4 (SiMe 2 N
