通过“浇铸聚合”制备的聚（BOL）膜在水溶液中表现出优异的分数溶质截留行为，在约200至1400的分子量范围内具有比较尖锐的边界区域，以及极高的水渗透性。这些显著的行为，以及大的吸水能力，可能是由于极性亲水和非极性疏水微区的一些微妙的安排可能形成沿着和之间的聚合物链。
The poly(BOL) membrane prepared by “casting polymerization” exhibited an excellent fractional solute-rejection behavior in the aqueous solution, having a comparatively sharp boundary region at the molecular weight range of about 200 to 1400, together with an extremely high water permeability. These conspicuous behaviors, as well as a great capacity for water absorption, may result from some delicate arrangement of polar hydrophilic and nonpolar hydrophobic microdomains probably formed along and between the polymer chains.
