Salt-like reaction products of hals derivatives and carboxylic acids for the stabilisation of polymeric materials

Process for the preparation of a saltlike reaction products comprising the step of reacting one or more HALS-compounds of general formula (I)

• wherein independently of each other
• A is —O— or —NR′—,
• R′ is H, or C1-C18-alkyl,
• R1 is C1-C18-alkyl, or two groups R1 bound to the same carbon atom form a C4-C8-cycloalkyl ring.
• R2 is H C1-C18-alkyl, or C7-C18-alkylaryl.
• r is a whole number between 0 and 3.
• with one or more organic acids of general formula (II)
• wherein independently of one another
• R6 is H, or a m-valent aliphatic, cycloaliphatic, aromatic or heteroaromatic residue,
• m is a whole number >0.

Process for the preparation a premanufactured mixture, wherein the mixture is formed by the reaction one or more HALS-compounds of general formula (I)

• wherein independently of each other
• A is —O— or —NR′—.
• R′ is H, or C1-C18-alkyl.
• R1is C1-C18alkyl, or two groups R1 bound to the same carbon atom form a C4-C8-cycloalkyl ring.
• R2 is H C1-C18-alkyl, or C7-C18-alkylaryl,
• r is a whole number between 0 and 3
• and one or more organic acids of general formula (II)
• wherein independently of one another
• R6 is H, or a m-valent aliphatic, cycloaliphatic, aromatic or heteroaromatic residue,
• m is a whole number >0
• comprising the step of preparing the mixture, wherein the preparing step includes one of obtaining the mixture from a melt, compacting the mixture, granulating the mixture or mixing the mixture.
