| titleOfInvention | A kind of catalytic component, preparation method and application for vinyl polymerization |
| abstract | The invention discloses a kind of catalytic components for vinyl polymerization, including chromium compound, organo-aluminum compound and the organoboron compound being supported on carrier, the structural formula of the organoboron compound are shown in formula I.Wherein Y is N-R in each case identical or differently 0 、C‑R 2 Or C=O；It is connected with singly-bound or double bond between two adjacent Y；And when more than two Y are C-R 2 When, R 2 Between can bonding；Z and X is C, and substituent group, and bonding or non-bonding between Z and X are optionally connected on C；M and n is 0 or 1 in each case identical or differently, and is 0 when m with n differences.The present invention also provides the preparation methods of the catalytic component, and the ethylene rolymerization catalyst including the component.The catalyst improves the polymerization activity of chromium-based catalysts when for vinyl polymerization, while the molecular weight distribution of polyvinyl resin being made to broaden. |
