11674011 · 2023-06-13 · ·

A method for manufacturing a crosslinked polyolefin separator and the crosslinked polyolefin separator obtained therefrom are provided. The method includes non-grafted polyolefin having a weight average molecular weight of 300,000 or more and silane-grafted polyolefin having a weight average molecular weight of 300,000 or more. The method minimizes gel formation, a side reaction occurring in an extruder during the manufacture of the separator, and provides the separator having a uniform surface.

Container formed of a composite material including three-dimensional (3D) graphene

A container may be formed from a composite material including a combination of thermoplastic resin and polypropylene-graft-maleic anhydride (PPgMA) mixed with one another, a plurality of carbon particles mixed in the combination, and a plurality of pores formed in at least some of the mixed carbon particles. In some instances, the carbon particles may include a first region having a relatively low concentration of carbon particles, and a second region having a relatively high concentration of carbon particles. In various implementations, the plurality of pores may be formed in at least some of the mixed carbon particles, the thermoplastic resin, and the PPgMA. In some aspects, at least some of the pores may be configured to be infiltrated by the PPgMA.

Poly(alkylene co-adipate terephthalate) prepared from recycled polyethylene terephthalate having low impurity levels

This disclosure relates to an aliphatic-aromatic copolyester of poly(butylene-co-adipate terephthalate) that is prepared from recycled polyethylene terephthalate in the presence of titanium catalyst and a phosphorous containing compound. The copolyester is contaminated with little or no ethylene glycol and/or isophthalic acid, which are artifacts of preparing the copolyester from recycled PET. Advantageously, because there is little or no contamination from ethylene glycol and/or isophthalic acid in the copolyester, there is essentially no depression in the material's melting temperature.

The present invention relates to resin-modifying particles, each of which contains a glycidyl group-containing polymer (B) and a core-shell copolymer (C) at a composite state, and a vinyl chloride resin composition containing a vinyl chloride resin (A) and the resin-modifying particles, and the like.

THERMOPLASTIC RESIN COMPOSITION AND EXTERIOR MATERIAL INCLUDING THE SAME

The present disclosure relates to a thermoplastic resin composition and an exterior material including the same. The thermoplastic resin composition has low gloss and has mechanical properties and processability equal or superior to those of conventional ASA resins. The thermoplastic resin composition also has improved viscoelastic properties that can lead to excellent processability during the manufacture of a co-extruded product and excellent adhesion within the co-extruded product. The thermoplastic resin composition is also capable of reducing surface defects.

DIRECTLY ADHERING, TRANSPARENT HEAT-SEALABLE BINDER FOR THE COATING AND SEALING OF TRANSPARENT PLASTICS FOILS

A transparent, heat-sealable coating for transparent PET packaging foils can be provided by using a heat-sealable lacquer based on styrene-containing copolymers, on poly(meth)acrylates, on at least one polyester and optionally on a tackifier, and also the process for the sealing of a foil coated with this lacquer. It is surprising here that, despite the use of a rubber based on styrene-containing polymers that is not optically compatible with polyesters and polymethacrylate, the transparency of the heat-sealable coatings is still very high.

THERMOPLASTIC COMPOSITION, THERMOPLASTIC COMPOSITE, AND METHOD FOR PRODUCING THERMOPLASTIC COMPOSITE

The present invention relates to a thermoplastic composition, a thermoplastic composite, and a method for producing the thermoplastic composite. In the method for producing the thermoplastic composite, a polymer, an acid-modified lignin with a specific element content and a compatibilizer with a specific melt flow index and a specific maleic anhydride content are used to produce the thermoplastic composite. Hydroxy groups of the acid-modified lignin react with maleic anhydride groups of the compatibilizer to generate ester bonds via an in-situ reaction catalyzed by acidic groups of the acid-modified lignin to enhance compatibility between the polymer and the lignin, thereby increasing a mechanical strength of the resulted thermoplastic composite.
