    摘要: A “high internal phase polymeric emulsion” (“HIPPE”) composition is described which comprises an emulsion of a discrete phase (component A) and a continuous phase (component B), wherein the volume fraction of the discrete phase is the majority fraction (on a volume basis) of the total volume of the emulsion. A compatibilizer, component C, is used to lower the interfacial tension between the phases containing components A and B. A process is described for creating such HIPPE composition in which the A component is a colloidal polymer particle.

    摘要: Semicrystalline polyolefins with narrow molecular weight distributions characterized by a low polydispersity index (PDI) and selected from the families of homopolymers, statistical copolymers, block copolymers, and graft copolymers, can be blended with a low molecular weight fluid diluent to create gel fiber and film compositions. These gel compositions, when subjected to mechanical or thermomechanical processing, either before or after removal of the diluent, result in fiber or film compositions that combine high tensile strength with other desirable physical properties, such as high rigidity, large extension at break, and/or high recoverable elasticity. These desirable combinations of properties are superior to those obtained from gel-processed semicrystalline polyolefins that are substantially similar in composition and molecular weight, but that have large PDIs.

    摘要: Polyolefin block and graft copolymers comprised of two or more semicrystalline polyolefin blocks or grafts and one or more amorphous polyolefin blocks can be blended with a low molecular weight fluid diluent that preferentially locates within and swells the amorphous domains of the block or graft copolymer, while preserving the crystallinity of the semicrystalline block domains. After mechanical or thermomechanical processing, such compositions combine softness with high strength and high recoverable elasticity. Compositions are also disclosed whereby the diluent species is removed from the composition, either before or after the mechanical or thermomechanical processing, in order to create a strong elastic material with an ultra-low entanglement density within the amorphous domains.
