摘要： A delivery system containing an active agent within a polymeric material formed from a thermoplastic composition is provided. Through selective control over the particular nature of the thermoplastic composition, as well as the manner in which it is formed, the present inventors have discovered that a porous network can be created that contains a plurality of micropores and nanopores. The ability to create such a multimodal pore size distribution can allow the delivery rate of an active agent to be tailored for a particular use.

摘要： Microparticles that have a multimodal pore size distribution are provided, Notably, the pore structure of the present invention can be formed without the need for complex techniques and solvent chemistries traditionally employed to form porous microparticles. Instead, the microparticles contain a polymeric material that is formed from a thermoplastic composition, which is simply strained to a certain degree to achieve the desired porous network structure.

摘要： A thermoplastic composition that contains a rigid renewable polyester and a polymeric toughening additive is provided. The toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. An increase in the deformation force and elongational strain causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This can result in the formation of a plurality of voids adjacent to the discrete domains that can help to dissipate energy under load and increase impact strength. To even further increase the ability of the composition to dissipate energy in this manner, an interphase modifier may be employed that reduces the degree of friction between the toughening additive and renewable polyester and thus enhances the degree and uniformity of debonding.
摘要翻译： 提供了含有刚性可再生聚酯和聚合物增韧添加剂的热塑性组合物。 增韧添加剂可以作为可再生聚酯的连续基质中的离散物理区域分散。 变形力和伸长应变的增加导致可再生聚酯基体在与离散区相邻的那些区域发生剥离。 这可能导致形成与离散区域相邻的多个空隙，其可以帮助在负载下耗散能量并增加冲击强度。 为了进一步提高组合物以这种方式耗散能量的能力，可以采用降低增韧添加剂与可再生聚酯之间的摩擦程度的相间改性剂，从而提高剥离的程度和均匀性。

摘要： An oil absorbing material is generally provided. The oil absorbing material can includes sorbent particles having an average aspect ratio of about 5 to about 500 and a mean average particle diameter of about 10 μm to about 1 millimeter. The oil absorbing material comprises polypropylene, polyethylene, inorganic filler particles, and absorbent core material. In one embodiment, the sorbent particles can have an average specific surface area of about 0.25 to about 5.0 m2/g and can have a bulk density that is about 0.01 g/cm3 to about 0.8 g/cm3. Processes of making the oil absorbing material are also provided via a solid-state shear pulverization recycling process transforming absorbent article waste into the oil absorbing material. The process can include pulverizing the absorbent article waste to form sorbent particles while cooling the absorbent article waste in an amount sufficient to maintain the absorbent article waste in a solid state.
