Stéricky bráněné aminy sú vysokoúčinné světelné stabilizátory polymérov. Nevýhodou nízkomolekulových zlúčenín tejto skupiny je značná prchavosť a vypierateínosť.Sterically hindered amines are high-efficiency light stabilizers of polymers. A disadvantage of the low molecular weight compounds of this group is the considerable volatility and washability.

Příklad 1Example 1

Zmes 1,9 g (0,005 mol) dietylesteru kyseliny 2—(7,15-diazádispiro 5,1,5,3 hexadekán-15-yl)propándiovej a 0,34 g (0,005 mol) etándiolu v 10 ml suchého xylénu sa zahřeje na 100 °C a přidá sa 10 mg lítiumamidu. Zmes sa áalej zahrieva po dobu 4 h pri tej istej teplote, pričom reakčný etanol pomaly oddestilováva. Po uplynulom čase sa zvýši teplota na 130 až 135 °C a udržiava sa áalších 6 h, čím oddestiluje zvyšný reakčný etanol. Rozpúšťadlo sa oddestiluje a zvyšok sa podrobí vysokému vákuu v priebehu 2 h pri teplote 160 °C. Potom sa obsah banky nechá ochladit, rozpustí sa v 30 ml toluénu a premyje dňkladne destilovanou vodou. Toluénový roztok sa nakoniec vysuší bezvodým síranom sodným a přečistí aktívnym uhlím. Odpařením rozpúšťadla a vystavením zvyšku vysokému vákuu pri teplote 120 °C sa získá tuhý, práškovateTný polymér s teplotou topenia v intervale 45 až 58 °C priemarnou číselnou molekulovou hmotnostou 1 400.A mixture of 2- (7,15-diazadispiro-5,1,5,3-hexadecan-15-yl) propanedioic acid diethyl ester (1.9 g, 0.005 mol) and ethanediol (0.34 g, 0.005 mol) in 10 ml of dry xylene is heated. to 100 ° C and 10 mg of lithiumamide is added. The mixture is further heated for 4 h at the same temperature, while the reaction ethanol is slowly distilled off. After the time has elapsed, the temperature is raised to 130-135 ° C and held for a further 6 h, thereby distilling off the remaining reaction ethanol. The solvent was distilled off and the residue was subjected to high vacuum for 2 h at 160 ° C. The contents of the flask were then allowed to cool, dissolved in 30 ml of toluene and washed with well distilled water. The toluene solution is finally dried over anhydrous sodium sulfate and treated with charcoal. Evaporation of the solvent and exposure of the residue to high vacuum at 120 ° C gave a solid, pulverizable polymer having a melting point of 45-58 ° C with an average molecular weight of 1,400.
