In an embodiment, an article of manufacture includes a first component, a second component, and a thermal interface material. The thermal interface material is disposed between the first component and the second component and includes a polymeric phase-change material. In another embodiment, an article of manufacture includes a first component, a second component, and a thermal interface material disposed between the first component and the second component, the thermal interface material including a polymeric phase-change material, the polymeric phase-change material including a block copolymer formed from a diene, the diene formed from a vinyl-terminated fatty acid monomer having a chemical formula CH&#x2014;R&#x2014;C(O)OH and an ethylene glycol monomer having a chemical formula CHO.

Thermal interface materials including polymeric phase-change materials

In an example, a thermal interface material includes a polymeric phase-change material.

The present disclosure refers to an inkjet ink set comprising a black ink with a black pigment, a yellow ink with a yellow pigment, a cyan ink with a cyan pigment, a magenta ink with a magenta pigment and a white ink with a white pigment. At least one of the ink further contains a latex binder that is dispersed in the ink vehicle, and that includes a first heteropolymer including two or more aliphatic (meth)acrylate ester monomers or two or more aliphatic (meth)acrylamide monomers; and a second heteropolymer including a cycloaliphatic monomer and an aromatic monomer. The present disclosure refers also to a printing method using the ink set and to a system for printing the ink set.

The present disclosure refers to an inkjet ink composition comprising an ink vehicle including water; a white metal oxide pigment dispersed in the ink vehicle; and a latex binder, dispersed in the ink vehicle. The latex binder includes a first heteropolymer including two or more aliphatic (meth)acrylate ester monomers or two or more aliphatic (meth)acrylamide monomers; and a second heteropolymer including a cycloaliphatic monomer and an aromatic monomer. The present disclosure refers also to a printing method using such inkjet ink composition.

Inkjet ink composition

A self-healing composite material includes a polymer matrix, microcapsules filled with a ring-opening metathesis-active monomer (e.g., norbornene, norbornene derivatives such as ethylidene norbornene, or cyclooctadiene), and polymeric particles comprised of a polymer that is soluble in the monomer with which the microcapsules are filled and having catalytic endgroups derived from an olefin metathesis catalyst, such as a Grubbs'-type catalyst. In some embodiments, the polymer having catalytic endgroups is synthesized via solution polymerization of a ring-opening metathesis-active monomer (e.g., norbornene, norbornene derivatives, or cyclooctadiene) in the presence of an olefin metathesis catalyst (e.g., Grubbs' 1st generation catalyst). The polymer having catalytic endgroups may then be processed via a grinding operation, for example, to prepare the small polymeric particles. In other embodiments, the polymeric particles are synthesized directly as microparticles (e.g., microspheres, granules, beads, etc.) utilizing an analogous suspension polymerization.

A process for the production of a flame-retardant polymer is disclosed. The process includes reacting a polyol, for example glycerol, with an organophosphorus monochloride material to produce a phosphorus-functionalized polyol derivative. The process further includes reacting the phosphorus-functionalized polyol derivative with a polycarboxylic acid to form the flame-retardant polymer, wherein phosphorus is chemically bound to a polymer chain of the flame-retardant polymer.

In an example, a method of butadiene sequestration includes receiving an input stream that includes butadiene. The method includes directing the input stream to a first sulfur dioxide charged zeolite bed for butadiene sequestration via a first chemical reaction of butadiene and sulfur dioxide to form sulfolene.

Butadiene sequestration via sulfur dioxide charged zeolite beds

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.

Block copolymers in laminate manufacturing

A flame retardant block copolymer is prepared from renewable content. In an exemplary synthetic method, a bio-derived flame retardant block copolymer is prepared by a ring opening polymerization of a biobased cyclic ester and a phosphorus-containing polymer. In some embodiments, the biobased cyclic ester is lactide. In some embodiments, the phosphorus-containing polymer is a hydroxyl-telechelic flame retardant biopolymer prepared by a polycondensation reaction of a biobased diol (e.g., isosorbide) and a phosphorus-containing monomer (e.g., phenylphosphonic dichloride). In other embodiments, the phosphorus-containing polymer is synthesized from a dioxaphospholane monomer.

Flame retardant block copolymers from renewable feeds

An AB-type block copolymer for use in printed circuit board (PCB) fabrication is provided having a structure represented by the following formula: wherein Ris a silane pendant group that includes a silicon-containing moiety capable of bonding to a glass surface, and wherein Ris a matrix-reactive pendant group that includes at least one moiety (e.g., a vinyl-, allyl-, amine-, amide- or epoxy-containing moiety) capable of reacting with a base polymer.

Block copolymers

A lactide-functionalized polymer is synthesized by polymerizing a monomer capable of undergoing radical polymerization (e.g., styrenic, vinylic, acrylic, etc.) using a brominated lactide initiator via atom transfer radical polymerization (ATRP). In some embodiments of the present invention, the brominated lactide initiator is 3-bromo-3,6-dimethyl-1,4-dioxane-2,5-dione prepared by reacting lactide with N-bromosuccinimide in the presence of benzoyl peroxide.
