摘要：
In an embodiment, a polyamide composition, comprises an anionically polymerized polyamide; wherein the polyamide composition has a crystallinity of greater than or equal to 45 wt% as determined by DSC; and a porosity of greater than or equal to 10 vol% as determined based on the density of the polyamide composition. In another embodiment, a method of making the preceding polyamide composition, which comprises anionically polymerizing a monomer mixture comprising a cyclic lactam monomer, a solvent in which the cyclic lactam monomer is soluble, a catalyst, and an activator to form the anionically polymerized polyamide.
