  • Publication number: 20180362784
    Abstract: An additive elastomeric manufactured part is comprised of extrudates comprised of a reaction product of a multifunctional Michael donor and multifunctional Michael acceptor and a rheological modifier. The additive elastomeric manufactured part may have a high elongation and resistance to heat. Said part may be made by dispensing a mixture of the multifunctional Michael donor, multifunctional Michael acceptor, rheological modifier and a catalyst through a through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the mixture so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base. Subsequent layers are then formed on the initial layer by repeating the dispensing and movement on top of the initial layer and layers that follow.

  • Publication number: 20150267032
    Abstract: A composition comprising a phase separated block copolymer and an inorganic dielectric nanoparticle, wherein the nanoparticle is dispersed in the copolymer and is present primarily in one phase. For example, a Ti02 nanocomposite can be created via the in situ formation of Ti02 within a silane-grafted OBC. Taking advantage of the phase morphology of the OBC and the differential swelling of the hard and soft segments, due to their inherent crystallinity, enables the selective incorporation of Ti02 nanoparticles into the soft segments of the OBC.
