摘要：

Macroporous membranes based on terpolymers of 2,3-epoxypropylmethacrylate, N-vinyl-2-pyrrolidone, and ethylenedimethacrylate were prepared by radical suspension copolymerization and subsequently modified with ammonia. The membranes were characterized by their porosity, specific surface area, pore size, water permeability and mechanical properties. The low content of N-vinyl-2-pyrrolidone improves the mechanical properties of the membranes. The mechanism of formation of the macroporous structure and heterogeneities is discussed.
