SUPERCONDUCTIVE POLYACETYLENE FORMED VIA IRRADIATION OF A UREA INCLUSION COMPOUND WITH A REACTIVE DIIODOPOLYENE GUEST
A conductive polymer formed by the photochemical condensation polymerization of polyacetylene. E,E,1,4-diiodobuta-1,4-diene ICH=CHCH+CHI (DIBD) in a crystalline urea inclusion compound is illuminated with low power broad spectrum pulsed UV visible radiation to form an irradiated DIBD urea inclusion compound that exhibits superconductivity and can be configured into an energy storage device that is rechargeable via magnetic induction. Altnernatively, (E,E,E)-1,6-diiodohexa-1,3-5-triene may be used as the guest monomer that is polymerized in the crystalline urea inclusion compound and the resulting polyacetylene urea composite crystal may be formed into a circuit for use as a superconductor.

Block copolymers in laminate manufacturing
A block copolymer is synthesized by polymerizing a silane-functionalized norbornene monomer in the presence of a catalyst system that includes a Ziegler-Natta catalyst and cocatalyst, followed by sequential addition and polymerization of a matrix-reactive functionalized norbornene monomer. In some embodiments, an enhanced substrate for a PCB is produced by applying the block copolymer to a substrate that includes glass fiber, followed by applying the base polymer to the substrate having the block copolymer applied thereto.
