Description
Fremgangsmåte til stabilisering av syntetiske polyamider. Process for stabilizing synthetic polyamides.
Ved fremstilling av tekstilmaterialer og In the manufacture of textile materials and
andre formede gjenstander fra polyamider på-virker utsettelse for varme og lys i mange tilfelle i en alvorlig grad fibrenes bruddfast-het og forlengelse, samt også farven av mange ferdige gjenstander. For å forbedre polyami-ders motstandsdyktighet mot denne avbyg-ning ved innvirkning av lys og varme, er der tidligere anvendt forskjellige midler for å other shaped objects from polyamides exposure to heat and light in many cases affects the breaking strength and elongation of the fibers to a serious extent, as well as the color of many finished objects. In order to improve the resistance of polyamides to this degradation when exposed to light and heat, various means have previously been used to
stabilisere polyamidene, slik at de forblir ufor-andret etter at de er utsatt for varme og lys eller andre innvirkninger som kan frembringe uønskede forandringer i deres egenskaper. stabilize the polyamides, so that they remain unchanged after they are exposed to heat and light or other influences that can produce unwanted changes in their properties.
Ved hjelp av foreliggende oppfinnelse By means of the present invention
skaffes der en fremgangsmåte til stabilisering av syntetiske lineære polyamider mot innvirkning av varme, lys, fuktighet og oxygen, ved tilsetning av stabiliseringsmidler til de polya-mid-dannende utgangsmaterialer, den polya-mid-dannende reaksjonsblanding eller den varme polyamidsmelte. a method for stabilizing synthetic linear polyamides against the effects of heat, light, moisture and oxygen is obtained there, by adding stabilizers to the polyamide-forming starting materials, the polyamide-forming reaction mixture or the hot polyamide melt.
Det karakteristiske hovedtrekk ved fremgangsmåten ifølge oppfinnelsen er at der som stabiliseringsmiddel anvendes et alkylaminsubstituert cumarin i en mengde fra 0,05 til 2 vektprosent av reaksjonskomponentene. The characteristic main feature of the method according to the invention is that an alkylamine-substituted coumarin is used as stabilizer in an amount of from 0.05 to 2% by weight of the reaction components.
Polyamider som med fordel kan stabili-seres ved fremgangsmåten ifølge foreliggende oppfinnelse, er beskrevet f.eks. i U.S. patent-skrifter nr. 2 071 250, 2 071 253 og 2 130 948. Spesielt kommer to typer polyamider i be-traktning, nemlig de som kan fåes fra poly-meriserbare monoaminomonocarboxylsyrer og deres amiddannede derivater, såsom f.eks. Polyamides which can advantageously be stabilized by the method according to the present invention are described, e.g. in the U.S. patent documents Nos. 2,071,250, 2,071,253 and 2,130,948. In particular, two types of polyamides come into consideration, namely those which can be obtained from polymerizable monoaminomonocarboxylic acids and their amide-formed derivatives, such as e.g.
caprolactam, og de som kan fåes ved omset-ning av egnede diaminer og egnede dicar- caprolactam, and those which can be obtained by the reaction of suitable diamines and suitable dicar-
boxylsyrer eller amid-dannende derivater av tobasiske dicarboxylsyrer. carboxylic acids or amide-forming derivatives of dibasic dicarboxylic acids.
Eksempler på alkylaminsubstituerte cu-mariner som kan anvendes ved fremgangsmåten ifølge oppfinnelsen, er 7-methylaminocumarin, 7-dimethylaminocumarin, 7-ethylaminocumarin, 7-diethylaminocumarin, 8-methylaminocumarin, 8-dimethylaminocumarin, 8-ethylaminocumarin, 8-diethylaminocumarin, 7-propylaminocumarin, 8-propylaminocumarin, 7-butylaminocumarin, 8-butylaminocumarin, 7-diisopropylaminocumarin, 6-methylaminocumarin og 6-diethylaminocumarin. Anvendbare er likeledes 7-methylamino-4-methylcumarin, 7-ethylamino-3-methylcumarin, 8-ethylamino-4-methyl-cumarin og 7-diethylamino-4-methylcumarin. Examples of alkylamine-substituted coumarins that can be used in the method according to the invention are 7-methylaminocoumarin, 7-dimethylaminocoumarin, 7-ethylaminocoumarin, 7-diethylaminocoumarin, 8-methylaminocoumarin, 8-dimethylaminocoumarin, 8-ethylaminocoumarin, 8-diethylaminocoumarin, 7-propylaminocoumarin , 8-propylaminocoumarin, 7-butylaminocoumarin, 8-butylaminocoumarin, 7-diisopropylaminocoumarin, 6-methylaminocoumarin and 6-diethylaminocoumarin. Also usable are 7-methylamino-4-methylcoumarin, 7-ethylamino-3-methylcoumarin, 8-ethylamino-4-methylcoumarin and 7-diethylamino-4-methylcoumarin.
Den mengde alkylamino-substituert cumarin som kan tilsettes ifølge oppfinnelsen er fra 0,05 til 2 vektprosent. Den nøyaktige mengde alkylaminosubstituert cumarin som er nødvendig for å oppnå den ønskede stabilisering i et gitt tilfelle, kan en fagmann bestem-me ved å utføre et enkelt forsøk. The amount of alkylamino-substituted coumarin that can be added according to the invention is from 0.05 to 2% by weight. The exact amount of alkylamino-substituted coumarin necessary to achieve the desired stabilization in a given case can be determined by a person skilled in the art by performing a simple experiment.
De alkylaminosubstituerte cumåriner som anvendes, tilsettes til polyamidene på et hvil-ket som helst passende trinn før fullførelsen av polymeriseringsreaksjonen. Herved inn-blandes stabiliseringsmidlet i polymerisatet og forblir således ikke bare på dets overflate. Herved oppnår man en meget langvarigere stabiliserende virkning enn hva der er mulig bare ved et ovetrekk på overflaten. The alkylamino substituted coumarins used are added to the polyamides at any convenient stage prior to completion of the polymerization reaction. In this way, the stabilizer is mixed into the polymer and thus does not just remain on its surface. In this way, a much longer-lasting stabilizing effect is achieved than is possible simply by overcoating the surface.
I det følgende beskrives som eksempel en utførelsesform for oppfinnelsen. In the following, an embodiment of the invention is described as an example.
Eksempel. Example.
En nylpnsaltoppløsning av omtrentlig ekvimolekylære mengder hexamethylen-diamin og adipinsyre ble fremstillet. Oppløsningen ble tilsatt 0,1 vektprosent 7-diethylamino-4-methylcumarin, hvorpå der ble fremstillet fibre av oppløsningen. Resultatene er oppført i nedenstående tabell. A sodium salt solution of approximately equimolar amounts of hexamethylenediamine and adipic acid was prepared. 0.1% by weight of 7-diethylamino-4-methylcoumarin was added to the solution, after which fibers were produced from the solution. The results are listed in the table below.
De resultater som ble funnet ved utset- The results found at exposure
