Use of monohydrate zinc acetylacetonate as halogenated polymer stabilizer and preparation method

摘要

The subject of the present invention is the use of zinc ateylacetonate comprising at least 4.4% by weight of water as halogenated polymer stabilizer.Its subject is likewise a process for the preparation of zinc acetylacetonate monohydrate, in which a zinc oxide and/or hydroxide and acetylacetone are brought into contact, in the presence of a solvent; the said solvent being used with a quantity of between 20 and 200 parts by weight, per 100 parts by weight of acetylacetone.
