摘要： The invention relates to a process for the preparation of polyalkyl-1-oxa-diazaspirodecane compounds, which can be used as highly active light stabilizers for polymers. The reaction is carried out in a solvent mixture of at least one alcohol and if appropriate an inert organic solvent in the presence of solid alkali metal hydroxide or a corresponding amount of a mixture of solid alkali metal hydroxide and water as the sole catalyst. The process offers the advantage that, by using a solvent mixture and dispensing with a phase transfer catalyst, a higher rate of reaction and therefore higher product quality with the same yield are achieved. By dispensing with a phase transfer catalyst, which remains in the waste water and must be disposed of expensively, and by the reusability of the solvent mixture, the process is more environment-friendly and more economical than processes known to date.

摘要： The present application relates to storage-stable plastics additives which are prepared by cooling a mixture of 99.9 to 10% by weight of molten additive material and 0.1 to 90% by weight of crystalline additive material after a shaping process. The shaping process is carried out by forcing the mixture out of a tool provided with die openings, and cooling can be carried out on a cooled conveyor belt. Even after prolonged storage and/or handling, these plastics additives remain free-flowing and do not stick.

摘要： The invention relates to a process for the preparation of polyalkyl-1-oxa-diazaspirodecane compounds, which can be used as highly active light stabilizers for polymers. The reaction is carried out in an inert organic solvent in the presence of solid alkali metal hydroxide or of the corresponding amount of a mixture of solid alkali metal hydroxide and water as the sole catalyst. The process offers the advantage that, by changing the reaction procedure in a multiphase system and avoiding the use of a phase transfer catalyst, equally good results are achieved with regard to product quality and yield. Additionally, it is possible to reduce the reaction time from over 6 hours to 30 minutes. This results in a considerable rise in the space-time yield and consequently contributes, in addition, to an increase in the economy of the process of the invention.
