Functional diphenylsulfone macromers having grafted polymer side chains, and copolymers and articles prepared therefrom.
Functional diphenylsulfone macromers with grafted polymer side chains and copolymers address fouling issues in porous polymer membranes by providing enhanced resistance and reduced extractability, improving separation efficiency and reducing pre-flushing requirements.

Abstract
Provided are functional diphenylsulfone macromers having grafted polymer side chains, copolymers having repeating units derived from functional diphenylsulfone macromers having grafted polymer side chains, and porous polymer articles containing these copolymers. The grafted polymer side chains contain repeating units derived from 2-oxazoline compounds. The porous polymer articles are typically membranes, which may be either flat sheets or hollow fibers. The porous polymer articles can be used to separate mixtures of biomaterials having different average sizes based on the average pore diameter of the porous polymer articles. For example, biomaterials such as bacteria, proteins, viruses, and cells can be separated based on size.
