In this review are reported some of the most relevant achievements in the chemistry of the ethylene-styrene copolymerization and in the characterization of the copolymer materials. Focus is put on the relationship between the structure of the catalyst and that of the obtained copolymer. On the other hand, the wide variety of copolymer architecture is related to the properties of the material and to the potential utility. [ABSTRACT FROM AUTHOR]

Highly linear 1-alkylbenzenes can be obtained in mild conditions and with good selectivity, through the homogeneous catalysis of olefin polyinsertion from cheap and largely available reagents. The comparison among some ansa metallocenes shows that the coordinative framework of the catalytic metal, by regulating the regiochemistry of the styrene insertion, determines upon the selectivity of the reaction.
