Pvc hollow filtration membrane and the preparation method thereof |
| abstract |
The present invention provides a polyvinyl chloride hollow filtration membrane, which mainly comprises the following components: 30-95 wt. % of polyvinyl chloride and 5-70 wt. % of vinyl chloride-vinyl acetate-maleic anhydride terpolymer, wherein the polymerization degree of polyvinyl chloride is from 700 to 2500; the content of vinyl acetate is 10-19 % and the content of maleic anhydride is 18-40 % on a basis of total weight of the terpolymer; and the absolute viscosity of the terpolymer is 1.2-1.9 mPa·s. A method for preparing such a polyvinyl chloride hollow filtration membrane is also provided in the present invention. |
