Enzymatic oxidative polymerization of pyrogallic acid for preparation of hindered phenol antioxidant
TL;DR: In this article, a novel antioxidant with high molecular weight was successfully synthesized via horseradish peroxide-catalyzed oxidative polymerization of pyrogallic acid, which is a black powder completely soluble in common organic solvents, has a number-averaged molecular weight of about several thousand and consists of phenylene and oxyphenylene units.

Chemiluminescence as an industrial test method for antioxidant effectiveness in polyolefins: II. Versatile application aspects
D.R. Kohler,C. Kröhnke +1 more
TL;DR: In this article, a direct comparison between oven ageing at T=135°C and chemiluminescence at T =150°C showed a good correlation between the two methods, therefore chemiluminance offers the same information on long term thermal stability in a much shorter time than the conventional oven ageing technique.

Calix[n]arenes—New light stabilizers for polyolefins
TL;DR: In this paper, a cascade mechanism is suggested for calix[ n ]arenes as light stabilizers for polyolefins, and the best stabilizers of this type are as effective as 2-hydroxybenzophenones.
