    Abstract: A polymeric material having anistotropic properties, such as mechanical properties (e.g., modulus of elasticity), thermal properties, barrier properties (e.g., breathability), and so forth, is provided. The anisotropic properties can be achieved for a single, monolithic polymeric material through selective control over the manner in which the material is formed. For example, one or more zones of the polymeric material can be strained to create a unique network of pores within the strained zone(s). However, zones of the polymeric material that are not subjected to the same degree of deformational strain will not have the same pore volume, and in some cases, may even lack a porous network altogether.

    Abstract: A film that comprises a thermoplastic composition that contains a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains is provided. The film is biaxially stretched in a machine direction and cross-machine direction to form a porous network in the composition. The porous network contains nanopores having a maximum cross-sectional dimension of about 800 nanometers or less. At least a portion of the nanopores are oriented in the cross-machine direction so that the axial dimension generally extends in the cross-machine direction and the cross-sectional dimension generally extends in the machine direction.

    Abstract: A thermoformed article that is formed from a polymeric sheet having a thickness of from about 0.1 to about 100 millimeters is provided. The polymeric sheet contains a thermoplastic composition that includes a continuous phase that includes a matrix polymer. A microinclusion additive and nanoinclusion additive are dispersed within the continuous phase in the form of discrete domains, and a porous network is defined in the composition that includes a plurality of nanopores having an average cross-sectional dimension of about 800 nanometers or less.

    Abstract: Polylactic acid fibers formed from a thermoplastic composition that contains polylactic acid and a polymeric toughening additive are provided. The present inventors have discovered that the specific nature of the components and process by which they are blended may be carefully controlled to achieve a composition having desirable morphological features. More particularly, the toughening additive can be dispersed as discrete physical domains within a continuous phase of the polylactic acid. These domains have a particular size, shape, and distribution such that upon fiber drawing, they absorb energy and become elongated. This allows the resulting composition to exhibit a more pliable and softer behavior than the otherwise rigid polylactic acid. Through selective control over the components and method employed, the present inventors have discovered that the resulting fibers may thus exhibit good mechanical properties, both during and after melt spinning.
