| abstract | (A) mindestens einen glycidyletherhaltigen amorphen und/oder semikristallinen Copolyester, (B) eine aliphatische und/oder cycloaliphatische mehrbasische Säure und/oder deren Anhydrid und/oder ein polyolmodifiziertes Anhydrid einer mehrbasischen Säure und/oder amorphe oder semikristalline carboxylfunktionelle Copolyesterharze und/oder carboxylfunktionelle Acrylatharze, (C) gegebenfalls Füllstoffe und/oder Pigmente und/oder Additive, wobei der glycidyletherhaltige amorphe und/oder semikristalline Copolyester ein Molekulargewicht (Mw) von 100 bis 15000 besitzt und dadurch erhältlich ist, daß in einem ersten Schritt ein amorpher und/oder semikristalliner Copolyester (D) hergestellt wird, der Hydroxylgruppen enthält, welcher dann anschließend in weiteren Schritten durch die Umsetzung mit Epihaloalkanen in den epoxidgruppenhaltigen Copolyester (A) übergeführt wird. The invention relates to new glycidyl ether-containing amorphous and / or semicrystalline copolyesters with a molecular weight (Mw) of 100 to 15000, which can be used as a component in coating compositions, also called powder coatings. The coating compositions contain the following components: (A) at least one amorphous and / or semicrystalline copolyester containing glycidyl ether, (B) an aliphatic and / or cycloaliphatic polybasic acid and / or its anhydride and / or a polyol-modified anhydride of a polybasic acid and / or amorphous or semicrystalline carboxyl-functional copolyester resins and / or carboxyl-functional acrylate resins, (C) optionally fillers and / or pigments and / or additives, the glycidyl ether-containing amorphous and / or semicrystalline copolyester having a molecular weight (Mw) of 100 to 15000 and being obtainable by an amorphous and / or semicrystalline copolyester in a first step (D) is produced which contains hydroxyl groups, which is then subsequently converted into the epoxy group-containing copolyester (A) in further steps by reaction with epihaloalkanes. n n n The invention further relates to a new, simple method for producing these new copolyesters and a method for producing the aforementioned powder coatings. |
