Description

Light-stabilized composition

The present invention relates to a light-stabilized composition comprising at least one polymer and 0.01 to 25 % by weight, based on the total weight of the composition, of a light-stabilizing component comprising at least one heptaazaphenalene compound of general formula (I),

(D

wherein the radicals R₁, R₂ and R₃ are defined in the description, optionally in combination with at least one further light stabilizer (Z), to articles, moulds, sheets, foils or films produced of such light-stabilized composition, to the use of at least one heptaazaphenalene compound of general formula (I) as a light stabilizer for polymers as well as to a light stabilizer combination comprising at least one of said heptaazaphenalene and at least one further light-stabilizer (Z).

Polymer compositions of various kinds are useful materials for many applications and are used in various industries as raw material for the production of various items such as for example articles or moulds of different size and shape, sheets, films, foils, paintings, coatings, as part of an end product or as end product for the consumer. Polymer compositions with high quality are replacing other materials such as glass, metal, paper and wood in an increasing extent. However, polymer compositions or articles thereof can be subject to rapid and severe degradation/deterioration because of exposure to light, impairing the mechanical properties like impact strength, flexibility or elasticity and causing discoloration, surface cracking or loss of gloss.

Despite the great diversity of already commercially available light stabilizers for polymers, there still exists a need for light stabilizers, which provide sufficient protection of a polymer composition against the deteriorating effect of light, especially in view of the global climate changes, which lead to an increase of sun light reaching the earth surface. Consequently, there is a need for an efficient protection of polymer compositions and items thereof against such increased exposure to sunlight and risk of light-induced degradation/decomposition.

Thus, it was an object of the present invention to provide polymer compositions, which are light stabilized, which means effectively protected against harmful degradation or decomposition caused/induced by light, such as e.g. UV light, sunlight or fluorescent indoor light.

This object was solved by the provision of the inventive light-stabilized composition comprising

at least one polymer and

0.01 to 25 % by weight, based on the total weight of the composition, of a light- stabilizing component comprising at least one heptaazaphenalene compound of general formula (I),

(I) wherein

the radicals Ri, R2 and R₃ are defined hereinafter.

Such inventive, light-stabilized compositions show an effective protection against deteriorating effects resulting from light exposure, preferably UV light.

Thus, one aspect of the present invention is a light-stabilized composition comprising at least one polymer and 0.01 to 25 % by weight, based on the total weight of the composition, of a light-stabilizing component comprising at least one heptaazaphenalene compound of general formula (I),

The term "light stabilizer" (also referred to as "photostabilizer" or "photoprotecting agent") means, according to the present invention a chemical compound that protects the material like a polymer against photodegradation against deterioriating and/or decomposing effects caused by its exposure to light. With respect to the definition of "light stabilizer" reference is made to the International Union of Pure and Applied Chemistry (IUPAC) Definitions of terms relating to polymer chemistry, Pure and Appl. Chem., Vol. 68, No.12, pp. 2313-2323, 1996.

Preferably, light stabilizers can also be classified according to their special possibility of stabilizing against the impact of light into absorbers, quenchers, peroxide decomposers or free radical scavengers.

So called absorbers and quenchers are preferably agents that reduce the impact caused by exposure to light either by absorbing, extincting, filtering, scattering, deflecting or reflecting light, a peroxide decomposer is preferably an agent that transforms peroxides into stable compounds without the formation of free radicals and a free radical scavenger is preferably an agent that eliminates free radicals by binding. Preferably, the inventive light-stabilized composition comprises as the light-stabilizing component at least one absorber, quencher, peroxide decomposer and/or free radical scavenger.

In a preferred embodiment of the present invention, the aforementioned further light stabilizers (Z) of the inventive light-stabilizing component are already known as stabilizers.

The inventive composition comprises preferably 0.001 to 25 % by weight, more preferably 0.01 to 25% by weight, most preferably 0.05 to 10% by weight, based on the total weight of the composition, of the light-stabilizing component.

In a preferred embodiment of the present invention, at least one of the light stabilizers of the inventive light-stabilizing component absorbs light in a wavelenth range from 100 to 700 nm, more preferably from 290 to 700 nm, most preferably from 290 to 400 nm. The term "absorption" according to the present invention means any of the following ways of reducing the exposure to light radiation, like absorbing, extincting, filtering, scattering, deflecting or reflecting of light radiation, since absorption only means the ratio of transmitted radiation to the incident radiation, without determining the mechanism according to which the light radiation is reduced.

In another preferred embodiment of the present invention, at least one light stabilizer of the inventive light-stabilizing component absorbs light in the range of UV-A (320 to 400 nm) and/or in the UV-B (290 to 320 nm) radiation.

In another preferred embodiment of the present invention, at least one light stabilizer of the inventive light-stabilizing component has a melting point >50°C, more preferably >100°C, more preferably >150°C, most preferably >200°C. In another preferred embodiment of the present invention the melting point for light stabilizers suitable for thermoplastic polymers is >100°C, more preferably >200°C.

Polymers can be preferably classified into four main groups:

1. Thermoplastic polymers

2. Thermosetting polymers/thermosets

3. Elastomers

4. Coordination polymers

1. Thermoplastic polymers

Plastics made of thermoplastic polymers is deformable, melts to a liquid when heated and freezes to a brittle, glassy state when cooled sufficiently. Most thermoplastic polymers are high molecular weight polymers whose chains associate through weak van der Waals forces (polyethylene), stronger dipole-dipole interactions and hydrogen bonding (nylon) or even stacking of aromatic rings (polystyrene). Thermoplastic polymers can not be remelted and remolded.

2. Thermosetting polymers

Thermosetting polymers ("thermosets") are materials that cure, through the addition of energy, to a stronger form. The energy may be in the form of heat (generally above 200⁰C), through a chemical reaction (two-part epoxy, for example), or irradiation. Thermoset materials are usually liquid, powder, or malleable prior to curing, and designed to be moulded into their final form, or used as adhesives. The curing process transforms the resin into a plastic or rubber by a cross-linking process. Energy and/or catalysts are added that cause the molecular chains to react at chemically active sites (unsaturated or epoxy sites, for example), linking into a rigid, 3-D structure. The cross-linking process forms a molecule with a larger molecular weight, resulting in a material with a higher melting point. During the reaction, when the molecular weight has increased to a point so that the melting point is higher than the surrounding ambient temperature, the material forms into a solid material. Subsequent uncontrolled reheating of the material results in reaching the decomposition temperature before the melting point is obtained. A thermoset material cannot be melted and re-shaped after it is cured. Thermoset materials are generally stronger than thermoplastic materials due to this 3-D network of bonds and are also better suited to high-temperature applications up to the decomposition temperature of the material.

3. Elastomers

The term elastomer is often used interchangeably with the term rubber, and is preferred when referring to vulcanisates. They are amorphous polymers existing above their glass transition temperature, so that considerable segmental motion is possible. At ambient temperatures rubbers are thus relatively soft and deformable. Their primary uses are for seals, adhesives and molded flexible parts. 4. Coordination polymers

Coordination polymers are compounds where the metals are bridged by polyatomic ligands, such as e.g. cyanide or carboxylates.
