Description

Method for preparing olefin-olefin alcohol copolymer

Technical Field

The invention belongs to the field of preparation of high molecular polymers, and particularly relates to a method for preparing an olefin-olefin alcohol copolymer.

Background

The polyolefin product has low price, excellent performance and wide application range. Under the condition of keeping the original excellent physical and chemical properties of the polyolefin, polar groups are introduced into polyolefin molecular chains by a chemical synthesis method, so that the chemical inertness, the printing property, the wettability and the compatibility with other materials can be improved, and new characteristics which are not possessed by raw materials are endowed. High pressure free radical polymerization is currently used commercially to promote direct copolymerization of olefins with polar monomers, such as ethylene-vinyl acetate, ethylene-methyl methacrylate, and ethylene-acrylic acid copolymers. Although the polar comonomer can be directly introduced into the polyolefin chain by high-pressure radical copolymerization, the method requires high-temperature and high-pressure conditions, and is high in energy consumption and expensive in equipment cost.

Ethylene-vinyl alcohol (EVOH or EVAL) copolymers are a novel polymer material that integrates processability of ethylene polymers and gas barrier properties of vinyl alcohol polymers, is one of three barrier resins industrially produced in the world at present, and is widely used for packaging foods, medical solutions and other products because hydroxyl groups contained in molecular chains form strong hydrogen bonds and form crystal portions that prevent gases such as oxygen from entering from the outside. Since vinyl alcohol cannot exist independently in the form of monomer, it is usually prepared by alcoholysis of ethylene-vinyl acetate copolymer by radical polymerization, but the alcoholysis process requires the use of a large amount of solvent, and the final saponification product contains a large amount of impurities such as acetic acid and alkali metal salt, and requires a large amount of water for washing.

As a preparation technology of polymers at normal temperature and normal pressure, coordination catalytic copolymerization has attracted extensive attention due to its remarkable effects in reducing energy consumption, improving reaction efficiency and the like. The catalyst participates in the reaction process, so that the activation energy of the copolymerization reaction of the olefin monomer and the polar monomer is greatly reduced, and the functional polymer with higher molecular weight can be obtained at lower temperature and pressure. Currently, only a few documents report the use of transition metal complexes to catalyze the copolymerization of olefins and unsaturated alcohols. Since EVOH has a large number of active hydroxyl groups in its molecule, even inside an extruder in an oxygen-free state, oxidation and crosslinking reactions may occur due to a high-temperature molten state, and a heat-degraded product may be generated, resulting in a gel-like mass that causes fish eyes. However, in the prior art, the polymer obtained by any method is a viscous massive solid, so that the polymer is easily scaled in polymerization equipment, and the transportation, solvent removal, granulation and the like of the polymer are difficult.
