Description

Vynález sa týká polyamidu na báze kyseliny 2,3-bis (1,2,2,6,6-pentametyl-4-piperidyloxyjbutándiove] a sposobu jeho přípravy.The present invention relates to a 2,3-bis (1,2,2,6,6-pentamethyl-4-piperidyloxy) butanedioic acid polyamide and a process for its preparation.

Stéricky bráněné aminy sa vyznačuju vysokou fotostabilizačnou účinnosťou v různých polyméroch, najma polyolefínoch. Nevýhodou nizkomolekulových zlúčenín tfejto skupiny je ich značná prchavosť, vykvetanie a extrahovatefnošť z polymérnych materiálov.The sterically hindered amines are characterized by high photostabilizing activity in various polymers, in particular polyolefins. A disadvantage of the low molecular weight compounds of this group is their considerable volatility, flowering and the extractability of polymeric materials.

Riešenie týchto problémov může poskytnúť použitie stabilizátorov s vyššou molekulovou hmotnosťou.The use of higher molecular weight stabilizers may provide a solution to these problems.

kde R je metylová alebo etylová skupina, posobí 1,6-hexándiamínom III v suchom xylene v přítomnosti metanolátu sodného, lítiumamidu alebo tetraalkyltitanátu pri teplote v rozmedzí od 110 do 160 °C po dobu 6 až 10 hodin.wherein R is methyl or ethyl, it is treated with 1,6-hexanediamine III in dry xylene in the presence of sodium methoxide, lithium amide or tetraalkyl titanate at a temperature ranging from 110 to 160 ° C for 6 to 10 hours.

Výhodou uvedeného vynálezu je příprava oligomérneho až polymérneho světelného stabilizátora polyalkylpiperidínového typu so zvýšenou molekulovou hmotnosťou, ktorý do značnej miery může eliminovat spomínané nedostatky vyskytujúce sa u nízkomolekulových zlúčenín tejto skupiny.An advantage of the present invention is the preparation of an oligomeric to polymeric light stabilizer of polyalkylpiperidine type of increased molecular weight, which can largely eliminate the aforementioned drawbacks of the low molecular weight compounds of this group.

2,3-bis (1,2,2,6,6-pentametyl-4-piperidyloxy)butándiovej, 0,232 g (0,002 móluj 1,6-hexándiamínu v 10 ml suchého toluénu, zahriatej na 110 °C sa přidá 0,05 g lítiumamidu ako katalyzátora. Zmes sa zahrieva 1 hodinu pri tej istej teplote, pričom časť reakčného metanolu sa pomaly oddestiluje. Potom sa teplota zvýši na 130 až 135 °C a udržiava sa po dobu 5 hodin. Počas tejto doby oddestiluje zvyšná časť reakčného metanolu a teplota sa zvýši na 160 °C. Po odstránení rozpúšťadla sa zvyšok pri nezmenenej teplote podrobí vákuu 0,1 kPa po dobu dalších 4 hodin. Po ochladení sa surový polymér rozpustí v 20 ml toluénu, přečistí aktívnym uhlím, dokladné premyje destilovanou vodou a roztok sa vysuší bezvodým síranom sodným. Po odpaření toluénu a vysušení zvyšku vo vákuovej sušiarni pri teplote 120 °C a tlaku 0,2 kPa po dobu 4 hodin sa získá tuhý, biely 1'ahko spráškovatetný polymér s teplotou máknutia v rozmedzí 79 až 83 °C, ktorý vykazuje pri použití metódy VPO priemernú číselnú molekulovú hmotnost v rozmedzí hodnot 2 600 až 2 700.2,3-bis (1,2,2,6,6-pentamethyl-4-piperidyloxy) butanedioic acid, 0.232 g (0.002 mol of 1,6-hexanediamine) in 10 ml of dry toluene heated to 110 ° C was added 0.05 The mixture is heated at the same temperature for 1 hour, while a portion of the methanol is slowly distilled off, then the temperature is raised to 130-135 ° C and maintained for 5 hours, during which time the remainder of the methanol is distilled off and The temperature is raised to 160 [deg.] C. After removal of the solvent, the residue is subjected to a vacuum of 0.1 kPa for a further 4 hours at an unchanged temperature.After cooling, the crude polymer is dissolved in 20 ml of toluene, purified with charcoal, thoroughly washed with distilled water. Evaporation of toluene and drying of the residue in a vacuum oven at 120 ° C and 0.2 kPa pressure for 4 hours gave a solid, white, easily dustable polymer having a softening temperature of 79-83 ° C, which, when used in the VPO method, has an average number molecular weight in the range of 2 600 to 2 700.
