摘要:
Oxygen scavenging materials incorporated into or attached to a package such as a gable-top or rectangular carton, used to package foods, beverages or other oxygen sensitive materials, and thereby increase shelf-life by decreasing oxygen in the headspace of the package, and decreasing oxidation of the packaged product.
摘要:
A process for selectively making 2-alkenes from a NAO using a mesoporous catalyst that has been surface modified with a Brönsted acid compound. The Brönsted acid compound has a reactive silane connector, an organic linking group, and a Brönsted acid group. The mesoporous catalyst has an average pore diameter in a range of about 12 to about 100 Angstroms and a surface area of between about 400 to about 1400 m2/gram.
摘要:
A family of polymers containing selected cyclic allylic pendent groups for oxygen scavenging packaging which has minimal organoleptic by-products after oxidation.
摘要:
Herein are disclosed modified vinyl alcohol polymers (mPVOH), wherein the mPVOH can comprise structure VII: and at least one structure comprising structure IX: or structure X: wherein —R can independently comprise an unsubstituted hydrocarbon moiety comprising at least one alpha hydrogen or a substituted hydrocarbon moiety comprising at least one alpha hydrogen. The mPVOH can be useful in oxygen barrier applications, such as a forming an oxygen barrier layer of a packaging article. Also disclosed are methods of forming mPVOH and methods of using mPVOH to make packaging articles with a superior barrier to entry by atmospheric oxygen.
摘要:
An oxygen scavenging composition or system is provided comprising an oxygen scavenging material, a photoinitiator, and at least one catalyst effective in catalyzing an oxygen scavenging reaction, wherein the photoinitiator comprises a benzophenone derivative containing at least two benzophenone moieties. A film, a multi-phase composition, a multi-layer composition, a multi-layer film, an article comprising the oxygen scavenging composition, a method for preparing the oxygen scavenging composition, and a method for scavenging oxygen are also provided. Non-extractable benzophenone derivative photoinitiators and methods for preparing same are also provided.

摘要:
Polycarbonate resins can be stabilized against the adverse influence of UV light by incorporating an effective amount of a methyl benzoate ester stabilizer by means of a coating on the surface of the resin.
摘要:
This invention relates to coating compositions prepared by prehydrolyzing the silane function of a silylated ultraviolet radiation screening compound and adding it to an aqueous silicone resin composition. Hydrolyzing the silane function renders the ultraviolet screen a silanol which is a compatible component in the silicone resin compositions contemplated.
摘要:
Alkoxysilylbenzotriazoles are provided and method for making such materials. These alkoxysilanes have been found useful as UV stabilizers and as adhesion promoters for silicone top coat compositions which can be applied onto thermoplastic organic polymers to impart improved abrasion resistance and UV stabilization thereto.
