20080319116 | Soft and strong elastomeric compositions from semicrystalline-amorphous polyolefin block copolymers - 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. | 12-25-2008 |

20100063213 | GEL-PROCESSED POLYOLEFIN COMPOSITIONS - 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. | 03-11-2010 |
20120326073 | POLYMER ELECTROLYTES BASED ON POLY(GLYCIDYL ETHER)S - A polymer electrolyte composition including a metal salt and at least one polymer comprising a poly(glycidyl ether), where the at least one polymer is amorphous at ambient temperature. The poly(glycidyl ether) polymer can be a blend of poly(glycidyl ether) polymers, can be a poly(glycidyl ether) polymer blended with a mechanically strong solid polymer, and can be a block of a block copolymer that also includes a polymer block forming a mechanically strong solid polymer. | 12-27-2012 |
