Definitions
- the invention relates to a molding composition with UV absorbers, processes for their preparation and applications.
- UV absorbers Since UV rays often lead to unwanted decomposition reactions, plastics often use UV-absorbing additives. These absorb in the UV region of the spectrum and thus protect either the polymer itself, other constituents of the plastic or an underlying material from such reactions. Such UV absorbers in addition to their advantageous protective function also have a number of disadvantages. Thus, their Absorbtionsbande extends into the visible area, which is why parts of the visible violet and blue light are absorbed and the plastic receives a yellowish hue. This is all the more unsatisfactory, as often only a small portion of the UV absorber used is actually needed to fulfill the protective function.
- a transparent component consists of a UV-stabilized molding compound, but the UV light can only penetrate into the uppermost layers due to the absorption of the stabilizer.
- the lower UV absorber has no stabilizing function, but due to its above-described absorption in the visible range, it contributes to increasing the yellowness value.
- EP 1115792 B1 and EP 939093 B1 describe the use of photo-fries-capable groups as pre-UV absorbers in polyesters and pofycarbonates.
- resorcinol is incorporated as a diol component in the main chain.
- Po y (meth) acrylates are not mentioned in these protective rights.
- EP 120608 describes polymers for coating applications prepared by the reaction of the OH group of resorcinol mono-benzoate with reactive groups of a polymer.
- polymers containing glycidyl methacrylate are reacted.
- the resorcinol mono-benzoate group can transform under UV light in a photo-Fries rearrangement to the o-hydroxybenzophenone group, which is an effective UV absorber.
- the process described has serious disadvantages:
- the preparation of the polymers can be carried out with this pre-UV absorber exclusively polymer analogous, since a corresponding methacrylic ester would prevent radical polymerization due to its radical scavenging effect.
- the polymer-analogous conversion to the desired "polymer-bound pre-UV absorber is disadvantageous because of the additional process step Epoxide groups undergo unwanted side reactions such as hydrolysis and cross-linking. Therefore, the method described is unsuitable for molding compositions.
- the object is achieved with a molding composition, characterized in that at least one monomer A with at least one monomer B, with a pre-UV absorber group, which by the action of UV light significantly increased absorption at a wavelength between 300 and 400 nm contains, is radically copolymerized.
- the compounds according to the invention can undergo a photo-Fries rearrangement under UV action in the solid polymer, the rearrangement product having the desired UV absorption.
- monomer B all compounds which, after copolymerization with monomer A under UV light, carry out photo Fries rearrangement reactions are suitable as monomer B.
- monomer B preference is given to using compounds having acryloyl or methacryloyl or styrenic structures, more preferably p-methylphenyl methacrylate.
- derivatives are also suitable, which may also contain branched or unbranched alkyl groups with Ci to C-i ⁇ , but also -O-CH 3 in para-position instead of a methyl group.
- Suitable monomers A are compounds which are selected from the group of free-radically polymerizable monomers. Particularly preferred monomers A are selected from the group of acrylates, methacrylates, substituted or unsubstituted styrenic monomers or acrylonitrile.
- the monomers B represent a pre-UV absorber which has no absorption band extending into the visible range. It has been found that the yellowness of the copolymer of monomer A and monomer B is not significantly worse than that of the yellowness of the pure molding material of monomer A.
- the polymer can also be processed well thermoplastic.
- blends with excellent properties can be prepared from the copolymers of monomer A and monomer B with further polymers.
- core-shell polymers can be prepared whose structure comprises, for example, a hard core, a rubber-elastic middle layer and an outer shell of polymethymethacrylate.
- the pre-UV absorber can be polymerized into the shell and / or the middle layer as needed.
- the bond to the polymer also proves to be advantageous over the pure physical interference, since there is no evaporation or sweating during processing. In addition, no migration from the component is to be feared.
- molded articles can be produced from the novel molding materials or blends. Usually semi-finished products, such as plates, sheets, blocks, profiles, tubes, hoses, rods, are produced.
- At least one monomer A is copolymerized free-radically.
- Usual additives e.g. suitable initiators or regulators are added.
- the reaction mixture is usually heated.
- Other polymers for the preparation of blends can also be added.
- the polymer is precipitated with a suitable solvent, dried and further processed.
- the reaction mixture may also contain dyes, impact modifiers and additives, e.g. Flame retardants, or inhibitors, lubricants or additives against the thermo-oxidative degradation may be added.
- moldings or semi-finished products are produced. Likewise, the molding compounds or blends can be applied to other materials or coextruded.
- the molding compositions according to the invention can also be used with other radical polymerization processes, such as e.g. emulsion polymerization,
- the molding composition according to the invention has a broad field of application. They can be used in the construction sector, in motor vehicles, rail vehicles, aircraft, watercraft, spacecraft and advertising technology. ' A particularly preferred field of application are films, Panels, coextruded layers on panels and exterior parts of motor vehicles.
- the molding composition according to the invention for UV adsorption by means of photo-floppye rearrangement is an inexpensive alternative to coextrusion in which only the upper layer is to be equipped with UV absorber.
- much more complicated geometries can be represented with the material according to the invention.
- the polymer is precipitated in methanol, dried (vac, 12O 0 C, 4h) and processed to a 1mm thick press plate (processing temperature: 18O 0 C).
- the press plate is irradiated in a SUN test CPS / 10 (ATLAS Material Testing Technology GmbH, D-63589 Linsen amount-Altenhasslau) with a power of 60 W / m 2 (measured in the wavelength range between 300-400 nm) and according to the irradiation times listed below in tabular form measured.
- the Yellowness Index is determined according to DIN 6167 (D65 / 1O 0).
