For example, "isomers" include cis- and trans- isomers, E- and Z- isomers, R- and S- enantiomers, diastereomers, D -isomers, L -isomers, racemic mixtures thereof, and other mixtures thereof , as within the scope of the invention. NOB1 en. Must add These later generation catalytic systems suffer from long and complicated synthesis and undesirable induction times before polymerization starts. Examples of such groups include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, 1-methylcyclopropyl, 1-ethylcyclopropyl, 1-propylcyclopropyl, 1- butil-ciklopropil-, 1-pentil-ciklopropil-, 1-butil-l-metil-ciklopropil-, 1,2-dimetil-ciklopropil-, 2-etil-l-metilciklopropil-, ciklooktil-, ciklononil- vagy ciklodecilcsoportot adhatjuk meg.
