A description is given of powder coating compositions comprising a) an organic film-forming binder and b) as stabilizer at least one compound of the benzofuran-2-one type. Powder coating compositions stabilized in this way reduce the discoloration of coatings during thermal curing, especially gas oven curing.
粉末涂料组合物包括 a) 有机成膜粘合剂和 b) 至少一种苯并呋喃-2-酮类化合物作为稳定剂。以这种方式稳定的粉末涂料组合物可以减少涂料在热固化(尤其是气炉固化)过程中的变色。

A mixture of a polyester or a polyamide, such as poly(ethylene terephthalate) PET, and a suitable stabilizer selected from the group consisting of certain Mannich base compounds, when extrusion compounded exhibits a lower residual acetaldehyde content than does PET or polyamide alone when similarly treated. The invention pertains to any polyester or polyamide used in the manufacture of molded articles, fibers or films, for instance bottles or containers which are used to store consumer materials, for example food, beverages and water.

application in the electrochemically‐driven CO2 reduction catalysis are presented. The work was aimed to investigate the impact of 1) two metalions in close proximity and 2) an internal proton source on catalysis. Therefore, three different Re complexes, a binuclear one with a central phenol unit, 3, and two mononuclear, one having a central phenol unit, 1, and one with a methoxy unit, 2, were utilised
