An object comprising: a blend of (i) a phenol-containing polymer and (ii) a nitrile butadiene rubber; wherein the phenol-containing polymer is present in an amount of at least 5 wt % and up to about 95 wt % by total weight of components (i) and (ii). The object may further contain an electrically conducting component dispersed within the blend or on a surface of the blend. Also described is a method of thermal-activated reversible mechanical deformation of the object by (i) deforming the object at a first temperature, which is at or above the glass transition temperature of the object, and applying a stress on the object; (ii) fixing the deformed state by cooling the object to a second temperature of no more than 0 C. while under stress, and removing the stress; and (iii) recovering the object to the original shape by raising the temperature of the object to the first temperature.

FDisclosed herein are compositions including a thermoformable sheet having three of more layers. Two layers include one or more monovinylidene aromatic monomer containing polymers which are impact modified by a rubber, one or more monovinylidene aromatic monomer and unsaturated nitrile containing copolymers, or a blend of one or more monovinylidene aromatic monomer containing polymers and a polyolefin, which exhibit resistance to environmental stress cracking. At least one of the two layers is an outer layer. An inner layer includes post-consumer recycled monovinylidene aromatic monomer containing polymers which are impact modified by a rubber, post-industrial recycled monovinylidene aromatic monomer containing polymers which are impact modified by a rubber. Optionally, the composition may include virgin monovinylidene aromatic monomer containing polymers which are impact modified by a rubber. Optionally, the composition may include an outer layer which is a gloss layer.

The present invention relates to the use of multiblock copolymer compositions as sacrificial materials for 3D fused deposition modeling.

A glazing having switchable optical properties is described, including a transparent substrate having an outer surface and an inner surface, a reflection layer on the outer surface and/or on the inner surface and a switchable functional element arranged on the interior side with respect to the reflection layer. The reflection layer contains a material having a refractive index n.sub.R of 1.6 to 2.5. The product of the refractive index n.sub.R and the thickness d of the reflection layer is from 250 nm to 960 nm.

Disclosed embodiments include the formation of an article of manufacture by a process in which vibrations are generated in a bulk material disposed within a build chamber. The vibrations are focused within a section of the base material, and the focusing is controlled to cause the section of the base material to undergo a physical transformation to form at least a portion of the article of manufacture.

Methods of molding a barrel, such as a syringe barrel having very low draft, are disclosed. Thermoplastic syringes having very low interior draft angels are also disclosed.

A method for synthesizing polyacrylonitrile (PAN) polymer with a narrow molecular weight distribution is disclosed. The preferred PAN polymer has a PDI (Mw/Mn) of about 2 or less. Such PAN polymer is synthesized by controlled/living radical polymerization using a special RAFT (Reversible Addition-Fragmentation Chain Transfer) agent. Also disclosed is a method for producing carbon fibers from PAN polymer with low PDI.

The present disclosure provides a composite film, a producing method of the composite film, a T-die structure for producing such composite film, and the application of the composite film in curtains and composite fabrics. The composite film includes light-reflective resin regions and a light-absorptive resin region, the light-absorptive resin region is located between the light-reflective resin regions such that they are formed into an integrated composite structure. The integrated composite structure is formed by one-time extrusion molding. The composite film of the present disclosure has advantages such as a thin film thickness, high strength and a good shading effect. The fabric and the shading curtain made of the composite film have the characteristics of being highly shading, lightweight and durable, easy to be produced and the like.

Articles comprising an expanded polytetrafluoroethylene membrane having serpentine fibrils and having a discontinuous coating of a fluoropolymer thereon are provided. The fluoropolymer may be located at least partially in the pores of the expanded fluoropolymer membrane. In exemplary embodiments, the fluoropolymer is fluorinated ethylene propylene. The application of a tensile force at least partially straightens the serpentine fibrils, thereby elongating the article. The expanded polytetrafluoroethylene membrane may include a microstructure of substantially only fibrils. The articles can be elongated to a predetermined point at which further elongation is inhibited by a dramatic increase in stiffness. In one embodiment, the articles are used to form a covered stent device that requires little force to distend in the radial direction to a first diameter but is highly resistant to further distension to a second diameter (stop point). A large increase in diameter can advantageously be achieved prior to reaching the stop point.
