OR a spósoibu ich přípravy, kde R značí metylová alebo etylovú skupinu.OR and a process for their preparation, wherein R represents a methyl or ethyl group.

- Spósoib přípravy týchto zlúčenín, ktoré nie sú známe z literatúry, sa zakladá na reakcii dimetyl- alebo dietyleisteru kyseliny 2,5-di-brómhexandiovej s 7,15-diazadiispiro- [5,1,5, 3] -hexadekán-14,16-diónom.- The method for the preparation of these compounds, which are not known from the literature, is based on the reaction of 2,5-di-bromohexanedioic acid dimethyl or diethyl ether with 7,15-diazadiispiro- [5,1,5,3] -hexadecane-14, 16-dione.

Uvedené zlúčeniny móžu samotné plnit funkciu světelných stabilizátorov polymérov. Nevýhodou nízkomolekulových látok patriaciái áo lupiny štěřiéký bráněných ámínov je ich značná prchavosť a vypieratelnosť.These compounds can themselves act as light stabilizers for polymers. The disadvantage of low molecular weight substances belonging to lupine of the hindered amines is their considerable volatility and scrubbing.

Přípravou polymérnych světelných stabilizátorov sa tieto nedostatky odstránia. K tomuto účelu móžu slúžiť látky, ktoré sú predmetom vynálezu.The preparation of polymeric light stabilizers removes these drawbacks. The substances which are the subject of the invention can be used for this purpose.

3,6 g (0,01 molu) dietyleisteru kyseliny 2,5-dibrómhexandiovej v 15 ml bezvodého dimetylformamidu. Zmes sa ďalej zahrieva a mieša po dobu 3 hodin a nechá sa ochladit. Vyextrahuje sa trikrát éterom a spojené éterické extrakty sa dokladné premyjú vodou, vysušia bezvodým síranom sodným a éter sa odpaří. Získaný zvyšok sa prekryštalizuje z etanolu. Získá sa produkt v podobě bielej kryštalickej látky s t.t. — 197—200 °C. Elementárna analýza pre CggHggNjOg:3.6 g (0.01 mol) of 2,5-dibromohexanedioic acid diethyl ether in 15 ml of anhydrous dimethylformamide. The mixture was further heated and stirred for 3 hours and allowed to cool. It is extracted three times with ether and the combined ether extracts are washed thoroughly with water, dried over anhydrous sodium sulphate and the ether is evaporated. The residue is recrystallized from ethanol. Obtained as a white crystalline solid, m.p. - 197-200 ° C. Elemental Analysis for CggHggNjOg:

Po odpaření rozpúšťadla sa zo zmesi vylisovali fólie o hrúbke 0,2 mm pri tlaku 20 MPa a teplote 190 °C po dobu 30 sekúnd. Tesne před lisováním sa vzorky ešte predohrievali 1 minútu pri teplote 190 °C. Fólie sa ožarovali ortuťovou výbojkou o výkone 125 W vo vzdialenosti 7 cm od zdroja a ako filter sa použil100 parts by weight of unstabilized powdered polypropylene were impregnated in 0.1% w / w dichloromethane. parts 2,6-di-tert. butyl-4-methylphenol, 0.15 wt. % of calcium stearate and 0.2 wt. After evaporation of the solvent, 0.2 mm thick sheets were pressed from the mixture at 20 MPa at 190 ° C for 30 seconds. Just before pressing, the samples were preheated for 1 minute at 190 ° C. The films were irradiated with a 125 W mercury lamp at a distance of 7 cm from the source and a filter was used

Kým doba dosiahnutia karbonylového indexu 0,2 u čistého polypropylénu bola 480 hodin, stabilizovaný polymér nedosiahol túto hodnotu ani za 3000 hodin.1.6 wt. % copper sulfate solution. The degradation of the polymer was followed by the development of the hydroperoxide and carbonyl bands in the infrared spectra. While the time of reaching the carbonyl index of 0.2 for pure polypropylene was 480 hours, the stabilized polymer did not reach this value even after 3000 hours.
