Polyolefin epoxy resin and its preparation method and application

Abstract

The invention discloses polyolefin epoxy resin, a preparation method and application, and belongs to the field of preparation of functional polymer materials. Functional polyolefin is prepared by adding a catalyst in a polymerization process of a polar olefin monomer and a non-polar olefin monomer; the molar ratio of the non-polar olefin monomer to the polar olefin monomer is 1:(0.9-0.001); the catalyst is a Ziegler-Natta catalyst of which a main ligand or an auxiliary ligand contains a strong electron withdrawing group, a metallocene catalyst of which a main ligand or an auxiliary ligand contains a strong electron withdrawing group, a non-metallocene early transition metal catalyst of which a main ligand or an auxiliary ligand contains a strong electron withdrawing group or a non-metallocene late transition metal catalyst of which a main ligand or an auxiliary ligand contains a strong electron withdrawing group or a mixture thereof. A cocatalyst is not required during polymerization,so that a polymer contains few impurities and is relatively pure; the cost is low; polymerization or copolymerization of olefin monomers containing epoxy groups can be catalyzed, a technology is simple, the cost is low, an equipment requirement is low, the energy consumption is low, and the environment pollution is low.

Description

Technical field[0001]The invention belongs to the field of preparation of functional polymer materials, and specifically relates to a preparation method and application of polyolefin epoxy resin and polyolefin epoxy resin.Background technique[0002]The reaction conditions for free radical polymerization of ethylene initiated by peroxides are demanding. Only at high temperature (200-350℃) and high pressure (200-300MPa) can ethylene undergo free radical polymerization to synthesize LDPE, with a wide molecular weight distribution. It is difficult for ethylene, propylene and other olefins to undergo ATRP polymerization, anionic polymerization, cationic polymerization, ring-opening metathesis polymerization, metathesis cyclization polymerization, and acyclic diene metathesis polymerization.[0003]Supported Ziegler-Natta catalysts include Ti-based catalysts, Cr-based catalysts, V-based catalysts, and rare earth-based catalysts. They can effectively catalyze the homopolymerization of ethylen...

Problems solved by technology

Therefore, these catalyst systems cannot catalyze the polymerization or copolymerization of olefin monomers containing epoxy groups

For these reasons, there are still no reports on the polymerization or copolymerization of olefin monomers containing epoxy groups catalyzed by these catalyst systems until now.
