Abstract: The present application provides a metallocene compound, and a preparation method and application thereof. The metallocene compound of the present application includes a structure as shown in Formula a, where Ar is selected from a substituted or unsubstituted C6-C30 aryl; Cp? is selected from a substituted or unsubstituted cyclopentadienyl, indenyl, or fluorenyl; X is at least one of halogen, substituted or unsubstituted C1-C30 alkyl, alkoxy, substituted or unsubstituted C2-C30 dialkylamino, alkenyl, and substituted or unsubstituted C6-C30 aryl; and M is a transition metal element. The metallocene compound is suitable for catalyzing a C6-C30 long straight chain ?-olefin raw material and also a mixed long branched chain non-terminal olefin raw material, and may obtain a polymerization product with a target molecular weight according to demand.

Abstract: The present application provides a catalyst for copolymerization of ethylene and methyl methacrylate and an application thereof. The catalyst includes a main catalyst, and the main catalyst is obtained by compounding a compound of formula (I) and a compound of formula (II); a mole ratio of the compound of formula (I) to the compound of formula (II) is (1:49) to (49:1). The catalyst has an excellent catalytic activity, and a copolymer of ethylene and methyl methacrylate with a high molecular weight can be obtained, with a weight average molecular weight of not less than 1×105 g/mol.
