Abstract:
The invention is directed to improved poly(terephthalic acid diester)-poly(isophthalic acid diester) resins, and in particular to improved polyethylene terephthalate-polyethylene isophthalate resin formulations, the improved formulations containing nucleating and chain-branching agents. The improved formulations of the invention have particular utility in the manufacture of plastic bottles.
Abstract:
A stabilizer selected from alkaline earth metal hydroxides, oxides and silicates and alkaline earth metal salts of higher fatty acids and an antioxidant are incorporated into a resin composition comprising an ethylene/vinyl alcohol copolymer and a propylene resin or a carbonyl group-containing thermoplastic resin. The stability of the resin composition is improved, and deterioration of the resin composition such as gelation, discoloration or reduction of the gas barrier property is prevented when this composition is heat-molded into a vessel.
Abstract:
A composition comprising a matrix of an ethylene-vinyl alcohol copolymer having dispersed therein a granular drying agent in a particulate state, wherein the volume-area average diameter of the grains of drying agent having a long dia meter of not less than 10.mu. is not greater than 30.mu.. A multi-layer structure comprising layers of such a composition. The gas barrier property of the multi-layer structure is not substantially reduced after a retort treatment and thus, the multi-layer structure is extremely useful for packaging of food, especially packaging of retorted food.
Abstract:
PREPARATION OF A POLYOLEFIN FFOAM BY EXTRUDING A COMBINATION OF MATERIALS INCULDING A CHEMICALLY INERT, PARTICULATE NUCLEATION SYSTEM, AN EXPANDING AGENT TOGETHER WITH PETROLEUM NAPTHA WHICH PROMOTES FOAMING IN A LOW PRESSURE AMBIENT, AN IONOMER, AND A BARRIER MAATERIAL OF HIGH MELT STRENGTH WHICH IMPROVES THE PROPERTIES OF THE POLYMER AND ALSO SERVES DURING FOAMING AS A BLOCKING MECHANISM AGAINST POST-EXTRUSION CELL COLLAPSE.
Abstract:
It is provided a phyllosilicate having a layered structure in the form of platelets and comprising an intercalating agent between the platelets, wherein the intercalating agent is a polyester of a molecular weight of 274 to 30,000 g/mol, and wherein the phyllosilicate is other than a phyllosilicate modified through ionic interchange. It is also provides a polymer nanocomposite comprising a polyethylene terephthalate (PET) polymer an the phyllosilicate mentioned above, as well as preparation processes for the preparation of the intercalated phyllosilicate and the PET nanocomposite. The PET nanocomposite is particularly useful for packaging, particularly for food and drink packaging.
Abstract:
A film for use in a packaging structure, comprising a coating on the film surface which comprises a binder and a particulate protuberant component able to remove a volatile organic compound from an environment in contact with the film in the packaging structure. Also provided is a packaging structure comprising such a film and a package which comprises the packaging structure.
Abstract:
A coating composition comprising a polymer, such as a copolymer comprising alkylene monomers and unsaturated acid monomers, and at least one phyllosilicate, a product coated with said composition, a method of making said coating compositions and a method of making said coated products.
Abstract:
An adhesive having water vapour barrier properties, comprising an adhesive base composed of at least one reactive resin, at least one elastomer and optionally at least one tackifying resin, and optionally a solvent, is particularly suitable as a barrier adhesive when it comprises at least one multifunctional oligomeric alkoxysiloxane, said oligomeric alkoxysiloxane containing more than one polymerizable group and more than one alkoxy group.
Abstract:
A barrier adhesive for the encapsulation of an (opto)electronic arrangement comprising an adhesive base composed of at least one reactive resin having at least one activatable group, at least one polymer, especially an elastomer, optionally at least one tackifying resin, where the adhesive base has a water vapour permeation rate after the activation of the reactive resin of less than 100 g/m2d, preferably of less than 50 g/m2d, especially less than 15 g/m2d, a transparent molecularly dispersed getter material and optionally a solvent, wherein the getter material is at least one silane having at least one alkoxy group and at least one activatable group.
Abstract:
An electronic component has an organic member between two transparent substrates, in which outer peripheral portions of the two transparent substrates are bonded by a sealing material containing to melting glass. The low melting glass contains vanadium oxide, tellurium oxide, iron oxide and phosphoric acid, and satisfies the following relations (1) and (2) in terms of oxides. The sealing material is formed of a sealing material paste which contains the low melting glass, a resin binder and a solvent, the low melting glass containing vanadium oxide, tellurium oxide, iron oxide and phosphoric acid, and satisfies the following relations (1) and (2) in terms of the oxides. Thereby, thermal damages to an organic element or an organic material contained in the electronic component can be reduced and an electronic component having a glass bonding layer of high reliability can be produced efficiently.
