    摘要: In one embodiment, we disclose hardened olefin waxes and processes for preparing them. In another embodiment, we disclose oxidized olefin waxes having low viscosity and processes for preparing them. The waxes are suitable for use as polishes, coatings, or inks, among other uses. For example, a hardened olefin wax composition produced from a feedstock olefin wax composition by contacting the feedstock olefin wax composition with an oxygen-containing gas at a temperature greater than a melting point of the feedstock olefin wax composition, the hardened olefin wax composition having: a needle penetration value at 25° C. at least 5 percent less than a needle penetration value at 25° C. of the feedstock olefin wax composition; a a kinematic viscosity at 100° C. of up to about 200% greater than the kinematic viscosity of the feedstock olefin wax composition; and a saponification number less than 5 mg KOH/g hardened olefin wax composition.

    摘要: Herein is disclosed multilayer packaging articles comprising an oxygen barrier layer comprising ethylene/vinyl alcohol copolymer (EVOH) (an “EVOH oxygen barrier layer”); an oxygen scavenging layer adjacent thereto, wherein the oxygen scavenging layer comprises a polymer comprising an ethylenic backbone and a cycloalkenyl group having structure I: wherein q1, q2, q3, q4, and r are independently selected from hydrogen, methyl, or ethyl; m is —(CH2)n—, wherein n is an integer from 0 to 4, inclusive, and, when r is hydrogen, at least one of q1, q2, q3, and q4 is also hydrogen; and a third layer adjacent to the oxygen scavenging layer. In addition to the oxygen scavenging function, the oxygen scavenging layer functions as a tie layer to substantially inhibit delamination of the EVOH oxygen barrier layer from the third layer of the packaging article.
