摘要

B "METALOCENO LINKED ON POINT BY METILIN, Catalyst FOR OLEFINA POLICE, LIGANT AND PROCESS FOR LIGANT PREPARATION" D . A new class of metalocenes bound by methylene bridge, formula (I): in which M is a transition metal belonging to groups 3, 4, 5, 6, lanthanoids or actinides; X is a monoanionic sigma ligant; R may be a radical alkyl, cyclalkyl, arilla, alkylalkyl; R may be halogen, radical alkyl, cyclalkyl, arile, alkyl or arilayl-quila; p is from 0 to 3; m is from 0 to 2; and n is from 0 to 4. In addition, the corresponding binders are described,a new process for its preparation and catalytic systems containing so-called methylene bound metalocenes.
