Abstract

The invention discloses a tertiary amine derivative type chlorine-containing amphiphilic polymer and a separation membrane prepared from the polymer. The tertiary amine derivative type chlorine-containing amphiphilic copolymer is formed by polymerizing chlorine-containing macromolecules as a dispersing agent, a small molecule ester as a solubilizer and a chlorine-containing monomer and a tertiaryamine derivative type hydrophilic monomer as raw materials through a free radical suspension polymerization method, wherein the chlorine-containing macromolecular dispersing agent is obtained by carrying out solution copolymerization on a chlorine-containing monomer and a tertiary amine derivative type hydrophilic monomer in an organic solvent. According to the invention, the chlorine-containing macromolecular dispersing agent is adopted and has excellent dispersing effect on chlorine-containing monomers, and the small molecule ester solubilizer can improve the intermiscibility of hydrophilicmonomers and chlorine monomers, so that the high-hydrophilicity chlorine-containing amphiphilic copolymer can be prepared; the tertiary amine derivative type chlorine-containing copolymer can be independently used for preparing a separation membrane or can be blended with other resins to prepare separation membranes; and compared with the existing chlorine-containing separation membrane material,the tertiary amine derivative type chlorine-containing copolymer is good in hydrophilicity, pollution-resistant, low in cost and good in application prospect.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a tertiary amine derivative type chlorine-containing amphiphilic polymer and a separation membrane prepared from the polymer. Background technique [0002] PVC is a non-toxic, odorless white powder. It has good chemical stability and good plasticity. Except for a few organic solvents, it can resist acid, alkali and salt at room temperature; PVC has poor thermal stability and light resistance, and it can start to decompose and change color when it is above 140°C. Based on the above characteristics, PVC is mainly used in the production of profiles, profiles, pipe fittings, plates, sheets, cable sheaths, hard or soft tubes, blood transfusion equipment, and films. And in the process of use, through continuous research and modification, the application field of PVC has been greatly expanded. [0003] Polyvinylidene chloride has the characteristics of flame resistance, corrosion res...
