Abstract
A polymeric material having a multimodal pore size distribution is provided. The material is formed by applying a stress to a thermoplastic composition that contains first and second inclusion additives dispersed within a continuous phase that includes a matrix polymer. Through the use of particular types of inclusion additives and careful control over the manner in which such additives are dispersed within the polymer matrix, the present inventors have discovered that a unique, multimodal porous structure can be achieved.
