Abstract
Description
514 075 2 t.ex. akrylatoligomerer där hög molekylvikt och hög akrylatfiinktíonalitet kombineras med en för molekylvikten låg viskositet, vilket är ett ofia eftersträvat förhållande vid tillverkning och användning av t.ex. akrylatoligomerer och -monomerer. Vidare ger dendritiska strukturer, inkluderande hyperförgrenade molekyler och dendrimerer, en unik balans mellan till exempel filrnhårdhet, ythårdhet, vidhäfiriing och flexibilitet. Vid akrylering av dendritiska polyestrar har emellertid problem visat sig kunna uppstå under upparbetning och rening. Ett vanligt förfarande vid nämnda upparbetning och rening är bland armat urlakning av oreagerad akrylsyra med vatten. Denclritiska polyestrars höga molekylvikt och höga polaritet tenderar i dessa sammanhang att ge upphov till stabila eller tämligen stabila emulsioner, vilka markant försvårar nämnda upparbetning och rening. Det har emellertid helt överraskande visat sig att detta problem kan överkommas eller markant reduceras genom att före akrylering späda eller blanda en, eventuellt partiellt kedjeterminerad eller funktionaliserad, dendritisk polyester vilken har minst en terminal hydroxylgrupp med minst en alkohol, vilken har minst en hydroxylgrupp, en molvikt som företrädesvis är högst 2000, såsom 60-1500 eller 100-1000, och vilken företrädesvis är flytande vid en temperatur av 20-50°C eller genererar flytande blandningar med nänmda dendritiska polyester vid denna temperatur. Erhållen blandning alayleras därefter med sedvanliga och välkända förfaranden, såsom genom reaktion med minst en förening innefattande minst en akrylomättriad. En reaktionsblandning innefattande en akrylatkomposition, vilken i sig innefattar minst en dendritisk polyesteralcrylatoligomer och minst en akrylatmonomer, erhålles vid akryleringen. Akrylatkompositionen kan därefter utvinnas och renas med kända förfaranden, såsom urlakning med vatten, utan att störande stabila emulsioner bildas. Utöver detta underlättas i de flesta fall såväl akrylering som upparbetning och rening genom att polyester/alkoholblandningen normalt har lägre viskositet än däri ingående polyester. 514 075 2 e.g. acrylate oligomers where high molecular weight and high acrylate al inctionality are combined with a low molecular weight viscosity, which is an otherwise desired ratio in the manufacture and use of e.g. acrylate oligomers and monomers. Furthermore, dendritic structures, including hyperbranched molecules and dendrimers, provide a unique balance between, for example, film hardness, surface hardness, adhesion and flexibility. However, in the acrylic of dendritic polyesters, problems have been found to arise during reprocessing and purification. A common procedure in said work-up and purification is, among other things, leaching of unreacted acrylic acid with water. The high molecular weight and high polarity of the critical polyesters in these contexts tend to give rise to stable or rather stable emulsions, which markedly complicate said work-up and purification. However, it has quite surprisingly been found that this problem can be overcome or markedly reduced by diluting or blending, optionally partially chain-terminated or functionalized, dendritic polyester having at least one terminal hydroxyl group with at least one alcohol having at least one hydroxyl group, e.g. molecular weight which is preferably not more than 2000, such as 60-1500 or 100-1000, and which is preferably liquid at a temperature of 20-50 ° C or generates surface mixtures with said dendritic polyester at this temperature. The resulting mixture is then alaylated by conventional and well known methods, such as by reaction with at least one compound comprising at least one acrylomethyl triad. A reaction mixture comprising an acrylate composition, which itself comprises at least one dendritic polyester acrylate oligomer and at least one acrylate monomer, is obtained in the acrylation. The acrylate composition can then be recovered and purified by known methods, such as leaching with water, without the formation of disturbingly stable emulsions. In addition to this, in most cases both acrylation as well as reprocessing and purification are facilitated by the fact that the polyester / alcohol mixture normally has a lower viscosity than the polyester contained therein.

Ornrörning samt genombubbling av luft startades och lösningen värmdes till 55°C, varvid 3,27 g metansulfonsyra satsades. Reaktionsblandningen värmdes sedan ytterligare till 90°C, vid vilken temperatur reaktionsvatten började avgå. Temperaturen höjdes sedan under 180 min successivt från 90°C till ll0°C. Reaktionen fick fortgå vid denna temperatur under ytterligare 210 min, tills vatten slutade avgå. Reaktionsblandningen kyldes nu till rumstemperatur.Example 1 40.0 g of a dendritic polyester with theoretically 16 terminal hydroxyl groups (Boltorn® H 2 O, Perstorp Specialty Chemicals, Sweden), 160.0 g of a tri-functional polyalcohol (Polyol TP30®, Perstorp Specialty Chemicals, Sweden) were mixed and charged together with 163.8 g of axylic acid, 10 drops of nitrobenzene, 0.5 g of methoxyphenol and 425 ml of toluene in a three-necked flask equipped with a magnetic stirrer, gas inlet, water separator (Dean-Stark), cooler and oil bath. Stirring and bubbling of air were started and the solution was heated to 55 ° C, with 3.27 g of methanesulfonic acid being charged. The reaction mixture was then further heated to 90 ° C, at which temperature reaction water began to evaporate. The temperature was then raised for 180 minutes successively from 90 ° C to 110 ° C.

Fasseparation studerades i båda tvättningarna och fullständig separation av fasema erhölls i båda fallen inom 30 min.The room temperature reaction mixture was then poured into a 2 L beaker equipped with a magnetic stirrer and pH electrode. The solution was neutralized with stirring with 425 ml of 1% NaOH (aq) until a pH of 7.0 was reached. The mixture was poured into a 2 l separatory funnel and the time to phase separation was measured. Complete separation of organ phase and aqueous phase was obtained within 30 minutes. The aqueous phase was separated and the organ phase was then washed with 2 x 500 ml of water, separating the aqueous phase between washes. Phase separation was studied in both washes and complete separation of the phases was obtained in both cases within 30 minutes.
Den tvättade organfasen rullindunstades sedan under vakuum och genombubbling av lufi, varvid al-:rylerad slutprodukt erhölls som en lågviskös, klar och färglös vätska.The washed organ phase was then roller evaporated under vacuum and bubbling through lu fi to give the alkylated final product as a low viscosity, clear and colorless liquid.

Temperaturen höjdes sedan successivt till 113°C och reaktionen fick fortgå vid denna temperatur, tills vatten slutade avgå. Reaktionsblandningen kyldes nu till rumstemperatur.Stirring and bubbling of air was started and the solution was heated to 105 ° C, whereby reaction water began to evaporate. The temperature was then raised gradually to 113 ° C and the reaction was continued at this temperature until water stopped evaporating. The reaction mixture was now cooled to room temperature.
Den rumstempererade reaktionsblandningen hälldes sedan över till en 2 l bägare försedd med magnetornrörare och pH-elektrod. Lösningen neutraliserades under omrörning med 425 ml 1% NaOH (aq) tills ett pH på 7,0 uppnåtts. Blandningen hälldes över i en 2 l separertratt och tiden till fasseparation uppmättes. Fullständig separation av organfas och vattenfas erhölls efter separation över natt (> 12 h). Vattenfasen avskiljdes och organfasen tvättades sedan med 2 x 500 ml vatten, med avskiljning av vattenfas emellan tvättarna på samma sätt som ovan.The room temperature reaction mixture was then poured into a 2 L beaker equipped with a magnet stirrer and pH electrode. The solution was neutralized with stirring with 425 ml of 1% NaOH (aq) until a pH of 7.0 was reached. The mixture was poured into a 2 l separatory funnel and the time to phase separation was measured. Complete separation of organ phase and aqueous phase was obtained after separation overnight (> 12 hours). The aqueous phase was separated and the organ phase was then washed with 2 x 500 ml of water, separating the aqueous phase between the washes in the same manner as above.
Organfasen upparbetades på samma sätt som i exempel 1, varvid slutprodukten erhölls som en viskös, transparent, gulaktig produkt.The organ phase was worked up in the same manner as in Example 1, the final product being obtained as a viscous, transparent, yellowish product.
