ABSTRACT:
A process for forming a dialysis membrane utilizing a mixture of ion exchange resin components and thermoplastic resin components mixed together in a dry state and rotationally formed into a membrane. The rotational forming process includes rotational molding using temperature to conform the components to the shape of the mold as well as rotational casting using solvents and phase inversion to form the membrane. The resulting membrane is a smooth, dimensionally stable, efficient dialysis membrane.
