Spherical particles comprising carbon nanomaterial-graft-polyolefin and methods of production and uses thereof
A nonlimiting example method of forming highly spherical carbon nanomaterial-graft-polyolefin (CNM-g-polyolefin) particles may comprising: mixing a mixture comprising: (a) a CNM-g-polyolefin comprising a polyolefin grafted to a carbon nanomaterial, (b) a carrier fluid that is immiscible with the polyolefin of the CNM-g-polyolefin, optionally (c) a thermoplastic polymer not grafted to a CNM, and optionally (d) an emulsion stabilizer at a temperature greater than a melting point or softening temperature of the polyolefin of the CNM-g-polyolefin and the thermoplastic polymer, when included, and at a shear rate sufficiently high to disperse the CNM-g-polyolefin in the carrier fluid; cooling the mixture to below the melting point or softening temperature to form the CNM-g-polyolefin particles; and separating the CNM-g-polyolefin particles from the carrier fluid.
Thin film, manufacturing method and uses thereof
The present disclosure provides a thin film including a first thermoplastic polyolefin (TPO) elastomer which is anhydride-grafted. The present disclosure further provides a method for manufacturing the thin film, a laminated material and a method for adhesion.
Adhesive compositions and multilayered structures comprising functionalized polypropylene
Provided are functionalized polypropylene adhesive compositions having a desirable range of melt flow rate. These compositions are obtained by grafting at least one impact polypropylene copolymer or by co-grafting a blend containing at least one impact polypropylene copolymer and at least one random polypropylene copolymer. The polypropylene copolymer(s) are grafted with one or more ethylenically unsaturated carboxylic acids or derivatives of these acids, such as anhydrides. Maleic anhydride is a preferred grafting monomer. Also provided is a multilayer film or sheet structure containing at least one barrier layer and at least one adhesive layer produced from the functionalized polypropylene adhesive composition. The multilayer film or sheet structure may also contain at least one predominantly polypropylene-based layer. In addition, a multilayer film or sheet structure is provided in which a barrier layer or a primer layer is adjacent to at least one layer that is produced from a dry blend or a melt blend of the functionalized polypropylene adhesive composition with a polypropylene matrix polymer.
ISOTROPIZED READY-TO-USE PLASTIC PELLETS WITH HIGHLY ENTANGLED NANOFIBRILS AND METHOD OF PRODUCTION
Disclosed herein is a method for producing isotropized ready-to-use polymer pellets or granules that contain completely or substantially relaxed matrix molecules and entangled organic nanofibrils with long aspect ratios that will provide superior properties for the products without high cost. These pellets are cost-effectively produced using industrial-scale fiber spinning or melt-blowing/spun-bond equipment followed by an isotropizing pelletizer. These pellets enable one to mass-produce the micro-fibrillar or nanofibrillar composites with superior mechanical properties, because they are readily usable (ready-to-use) for industry-scale mass production systems with a very high throughput over 1000 kg/hr. The organic nanofibrils are well dispersed and entangled in the polymer matrix and have a long aspect ratio ranging hundreds to thousands, to tens of thousands. The nanofibrils are entangled with each other to have proper rheological properties for film or foam processing, and to have good mechanical properties of the final products.
Under layer film-forming composition for imprints and method for forming pattern
Provided is a composition for forming underlying layer for imprints, which is excellent in surface flatness and adhesiveness. The composition for forming underlying layer for imprints comprises (A) a resin having an ethylenic unsaturated group (P), and a cyclic ether group (T) selected from oxiranyl group and oxetanyl group, and having a weight-average molecular weight of 1000 or larger; and, (B) a solvent.
DEVICE AND METHOD FOR MANUFACTURING ABSORBENT BODY
A device for manufacturing an absorbent body includes: a shaping unit that includes a recessed portion and that makes liquid absorbent fiber and superabsorbent polymer to be deposited in the recessed portion, shaping the absorbent body; and a supply unit that supplies the liquid absorbent fiber and the superabsorbent polymer to the recessed portion. The recessed portion includes a protruding portion, and the protruding portion protrudes from a bottom surface and includes an inclined surface. In a cross section orthogonal to a ridge line of the protruding portion, an angle of the inclined surface with respect to a surface parallel to the bottom surface is greater than an angle of repose of the superabsorbent polymer and smaller than 90 degrees.
SEALANT FILM, MULTILAYER FILM INCLUDING SAME, PACKAGING BAG AND PACKAGING CONTAINER, AND METHOD FOR PRODUCING SEALANT FILM
