Abstract

The present invention discloses a strong lipophilic long chain Alpha-olefin amphiphilic graft copolymer and a preparation method thereof. The present invention takes a long chain Alpha-olefin-p-methylstyrene copolymer as the matrix; the polyethylene glycol with one hydroxyl terminal is grafted on the chain of the copolymer by a bromination reaction and an etherification reaction. A molecular structure (such as the grafting density and graft length) of the graft copolymer can be effectively controlled by the method. The preparation method of the strong lipophilic long chain Alpha-olefin amphiphilic graft copolymer which is related by the present invention has simple process and convenient operation, the graft copolymer can be fully dissolved in the non-polar solvent (such as, n-octane, petrol, diesel, etc.) under the room temperature, the present invention has the broad application prospect in emulsible oil, cosmetics, inverse emulsion polymerization, non-polar membrane surface modification and other fields.

Description

technical field

[0001] The invention relates to a strong lipophilic long-chain alpha-olefin amphiphilic graft copolymer and a preparation method thereof. Background technique

[0002] The inherent non-polarity of polyolefin makes its printability, adhesion and compatibility with other materials poor. Modified polyolefins can be widely used in polymer blends and composite materials. Therefore, the chemical modification of polyolefins has always attracted the attention of academia and business circles. How to introduce polar groups or polar polymers into polyolefins has gradually become a research hotspot in recent years. Most studies on amphiphilic copolymers are limited to the preparation of polystyrene and polyethylene oxide graft copolymers or block copolymers. There have been some reports in recent years on the research on amphiphilic copolymers of other polyolefins containing polar groups or polar polymers, such as the Institute of Chemistry, Chinese Academy of Science...
