    Abstract: The present invention provides thermal insulator composites based upon nanostructured L3-silica microparticles and polyurethane foam chemistry that are both easy to process and have superior insulating properties for use in household and commercial refrigeration, construction, and shipping applications. The composite material retains many of the attractive processing characteristics of polyurethane foams such as volume expansion and shape-filling during polymerization and demonstrates a total thermal conductivity between 32 and 44% that of commercially available polyurethane foams.

    Abstract: Using novel synthetic techniques, siloxane-urea segmented copolymers are made. The copolymers advantageously contain a polyether interface, with controlled morphologies and properties. High molecular weight, high strength siloxane-urea copolymers with a high content of urea hard segment may be prepared. Polymer properties that can independently be controlled include modulus, ultimate tensile strength, level of equilibrium water absorption and refractive index.

    Abstract: Using novel synthetic techniques, siloxane-urea segmented copolymers are made. The copolymers advantageously contain a polyether interface, with controlled morphologies and properties. High molecular weight, high strength siloxane-urea copolymers with urea hard segment contents ranging from 5 to over 60% by weight may be prepared. Polymer properties that can independently be controlled include modulus (1.0 to 120 MPa), ultimate tensile strength (1.5 to 25 MPa), level of equilibrium water absorption (˜0 to 100% by weight) and refractive index (1.43 to 1.46).

    Abstract: Novel segmented polyurethaneurea copolymers were synthesized using a poly(ethylene-butylene)glycol based soft segment. Dynamic mechanical analysis (DMA), small angle X-ray scattering (SAXS) and atomic force microscopy (AFM) established the presence of a microphase-separated structure in which hard microdomains are dispersed throughout a soft segment matrix. Wide angle X-ray scattering (WAXS) and differential scanning calorimetry (DSC) results suggest the materials are amorphous. Samples that are made with HMDI/DY and have hard segment contents in the range of 16-23 wt % surprisingly exhibit near-linear mechanical deformation behavior in excess of 600% elongation. They also show very high levels of recoverability even though their hysteresis is also considerable. The materials are both melt processable and solution processable.
