     For example, X1, X2, X4 and X5 in the compound of the general formula (I) are the same and are a group of the general formula (II)

     Most preferred compounds according to formula (5) are benzenepropanoic acid, 3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxy-,methyl ester corresponding to formula 
     
       
         
         
             
             
         
       
     
     (CAS Registry Number 84268-33-7);

     or the compound according to formula (5a) or (5b) having a chloro substituent corresponding to formula 
     
       
         
         
             
             
         
       
     
     Preferably, the compound according to formula (5) is a compound corresponding to formula (5a) or (5b). 
     Polyglycerol (CAS Registry Number 25618-55-7; 1, 2, 3-propanetriol, homopolymer) corresponding to formula (6) is known as a versatile building block for sustainable cosmetic raw materials (Wenk, H. H.; Meyer, J.; SOFW Journal, 2009, volume 135, issue 8, pages 25-30). 
     Polyglycerol is an ether linked homopolymer of glycerol, which is available in different degrees of polymerization, where higher polymers are associated with increasing hydrophilicity and molecular weight. Although the idealized structure of polyglycerol—a 1,3-linked, linear polymer is rather simple, the reality is much more complex. Polyglycerols are mixtures of a number of structures, which are defined by oligomer distribution, degree of branching, and amount of cyclic structures. Even products with the same average molecular weight may differ significantly in their properties. 
     The oligomerization of glycerol is a consecutive reaction, and complete conversion of glycerol favors formation of high molecular-weight glycerol oligo- and polymers. 
     The general structural formula for polyglycerol can be sketched from the following formula (8) as 
       HOCH 2 —CHOH—CH 2 —O—[CH 2 —CHOH—CH 2 —O] n —CH 2 —CHOH—CH 2 OH.  (8)
 
     wherein
 
n=0 results in diglycerol,
 
n=1 in triglycerol, n=2 in tetraglycerol etc., including branched isomers formed by reaction of secondary hydroxyls.
 
     Beside linear polyglycerol cyclic oligomers can be formed by further condensation (Diglycerin and hoehere Oligomere des Glycerins als Synthesebausteine, Jakobson, G., Fette, Seifen Anstrichmittel, 1986, volume 88, pages 101-106). 
     With the increase of molecular weight the hydroxyl number of polyglycerol decreases (diglycerol comprises 4, triglycerol 5, tetraglycerol 6 etc. hydroxy groups). In some embodiments, the glycerol-based composition is fractionated to produce the desired distribution of glycerol polymers and a desired hydroxyl value. 
     Detailed synthesis procedures for the preparation of polyglycerol are described in WO2011098315, WO2015122770, WO2002036534, US20020058781, U.S. Pat. No. 6,620,904 and WO2007092407. 
     Preferred catalysts for the preparation of polyglycerol are K 2 CO 3 , Li 2 CO 3 , Na 2 CO 3 , KOH, NaOH, CH 3 ONa, Ca(OH) 2 , LiOH, MgCO 3 , MgO, CaO, CaCO 3 , ZnO, CsOH, Cs 2 CO 3 , NaHCO 3 , CsHCO 3 , SrO and BaO. 
     The reaction is preferably carried out between 230 and 260° C. 
     Processes for the preparation of polyglycerol alkylates corresponding to the general formula (7) are also well known and are for example described in US2015 0164771, page 3, paragraph [0020], which is thus herewith incorporated by reference. 
     Polyglycerols and polyglycerol alkylates corresponding to the general formulae (6) and (7) are also commercially available from a great variety of sources. For example, polyglycerin #310, polyglycerin #500, polyglycerin #750, decaglycerol tri-stearate (TS-7S), decaglycerol deca-stearate (DAS-7S), hexaglycerol mono-stearate (MS-5S)hexaglycerol di-stearate (SS-5S) are available from Sakamoto Yakuhin Kogyo Co., Ltd., Japan. Natrulon H-6 (Polyglycerin-6), Natrulon H-10 (Polyglycerin-10), polyglyceryl-10 decaoleate (Polyaldo® 10-10-0), polyglyceryl-3 stearate (Polyaldo® 3-1-S), polyglyceryl-6 distearate (Polyaldo® 6-2-S), polyglyceryl-10 stearate (Polyaldo® 10-1-S), polyglyceryl-10 dipalmitate (Polyaldo® 10-2-P), polyglyceryl-10 oleate (Polyaldo® 10-1-0) and polyglyceryl-10 caprylate/caprate (Polyaldo® 10-1-CC) are available from Lonza AG, Switzerland. Polyglycerine-10, Polyglycerine-6, Polyglycerine-4, Polyglycerine-3 is available from Spiga Nord S.p.A., Italy. 
     The ultraviolet radiation absorbing composition according to the present invention is composed of a complex combination of different molecules (complex reaction products). 
     This is further illustrated in formula (Ia) representing a preferred polymer compound of the general formula (I) according to the present invention based on a polyglycerol backbone containing 5 glycerol units (examples without limitation): 
     
       
         
         
             
             
         
       
     
     The glycerol backbone typically consists mainly of 3 to 20 glycerol units, whereby the hydroxyl groups of the glycerol backbone are covalently linked to the benzotriazole UV chromophore. It might be reasonably assumed that primary hydroxyl groups (terminal units) react faster than secondary hydroxyl groups, which are less reactive for derivatization. Therefore, some secondary hydroxyl groups remain unreacted. The glycerol backbone consists of primarily linear and unbranched structure units. Branched isomers and higher molecular fractions including more than 20 glycerol units can be present. 
     Minor components e.g. benzotriazole conjugates of cyclic glycerol oligomers (examples without limitation):

     It has been specifically found out by the inventors that the ultraviolet radiation absorbing composition (UVRAP) can be used as UV absorbing agent for stabilizing a shaped artificial polymer article, wherein the polymer is a synthetic polymer or a natural elastomer. 
     Specific examples of a synthetic polymer or a natural elastomer are: 
     1. Polymers of monoolefins and diolefins, for example polypropylene, polyisobutylene, polybut-1-ene, poly-4-methylpent-1-ene, polyvinylcyclohexane, polyisoprene or poly-butadiene, polyhexene, polyoctene, as well as polymers of cycloolefins, for instance of cyclopentene, cyclohexene, cyclooctene or nor-bornene, polyethylene (which optionally can be crosslinked), for example high density polyethylene (HDPE), high density and high molecular weight polyethylene (HDPEHMW), high density and ultrahigh molecular weight polyethylene (HDPE-UHMW), medium density polyethylene (MDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), (VLDPE) and (ULDPE). 
     Polyolefins, i.e. the polymers of monoolefins exemplified in the preceding paragraph, preferably polyethylene and polypropylene, can be prepared by different, and especially by the following, methods: 
     a) radical polymerisation (normally under high pressure and at elevated tempera-ture). 
     b) catalytic polymerisation using a catalyst that normally contains one or more than one metal of groups IVb, Vb, VIb or VIII of the Periodic Table. These metals usually have one or more than one ligand, typically oxides, halides, alcoholates, esters, ethers, amines, alkyls, alkenyls and/or aryls that may be either π- or σ-coordinated. These metal complexes may be in the free form or fixed on substrates, typically on activated magnesium chloride, titanium(III) chloride, alumina or silicon oxide. These catalysts may be soluble or insoluble in the polymerisation medium. The catalysts can be used by themselves in the polymerisation or further activators may be used, typically metal alkyls, metal hydrides, metal alkyl halides, metal alkyl oxides or metal alkyloxanes, said metals being elements of groups Ia, IIa and/or IIIa of the Periodic Table. The activators may be modified conveniently with further ester, ether, amine or silyl ether groups. These catalyst systems are usually termed Phillips, Standard Oil Indiana, Ziegler (-Natta), TNZ (DuPont), metallocene or single-site catalysts (SSC).

     Determination of Sn by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) 
     The sample preparation was done by pressurized wet digestion in PTFE vessels: About 200 mg of the sample was treated with 3 ml HNC 3  at a temperature of about 150° C. for six hours and cooled down to room temperature. The obtained solution was diluted with deionized water to an end volume of 20 ml and directly measured by ICP-AES. 
     The calibration was done by external standard method with commercially available elemental standard solutions. As a typical apparatus a Varian Vista Pro ICP-AES or Agilent 5100 ICP-AES spectrometer can be used. 
     Specific wavelengths for evaluation: Sn, 189.924 nm for the quantitative evaluation as well as 133, 138, 143, 146 and 284 nm to check possible interferences. 
     Synthetic Procedure 
     1. Preparation of Polyglycerols 
     Different polyglycerols (or polyglycerol alkyl esters) may be prepared as described in WO 2002 036534, US 2002 0058781, JP 02172938 and U.S. Pat. No. 6,620,904. CaO, Na 2 CO 3  or Ca(OH) 2  is used as catalyst. If necessary, glycerol, diglycerol and other low molecular fractions can be removed from the reaction product, e.g. by short path distillation in order to achieve a specific quality. The characterization of the polyglycerols is outlined in table 1. 
     Polygycerols (or polyglycerol alkyl esters) are also available from Lonza AG, Sakamoto Yakuhin Kogyo Co. Ltd., Spiga Nord S.p.A., Evonik Industries AG.

     Example 1: Aging of Thermoplastic Polyolefins 
     Preparation of the Tested Specimen: 
     The components of the formulation listed in Tables 5a, 5b and 5c are pre-mixed in a high-speed mixer. This mixture is compounded in a twin-screw extruder Berstorff® ZE 25×32D at 230° C. under N 2  blanket. The full formulation is then injection molded at 230° C. on an Engel HL65 injection molding machine. The injection molded plaques (68 mm×44 mm×2 mm) are stored at elevated temperatures at 150° C. The parameters measured are stickiness according to PV1306, durability via 3-point bending test until embrittlement and color deviation (gray scale and Delta E*) and gloss at 60°. 
     The injection molded plaques are also exposed to artificial weathering according to Volkswagen Norm PV1306 (Stickiness Test) (Xenon light, irradiance 40 W/m 2 © 300-400 nm, black panel temperature 80° C., relative humidity 20%+/−10%) and Volkswagen Norm PV3930 (Florida Test) (Xenon light, irradiance 60 W/m 2 © 300-400 nm, black panel temperature 65° C., relative humidity 35-45%+/−5%). The parameters measured are stickiness according to PV1306, color deviation (gray scale and Delta E*) and gloss at 60°. 
     The inventive examples IE11 and IE12 show superior performance.

     Example 2: Aging of ABS 
     Preparation of the Tested Specimen: 
     The components of the formulation listed in Tables 6a, 6b, 6c and 6d are pre-mixed in a highspeed mixer. This mixture is compounded in a twin-screw extruder Berstorff® ZE 25×32D at 230° C. under N 2  blanket. The full formulation is then injection molded at 230° C. on an Engel HL65 injection molding machine. The injection molded plaques (68 mm×44 mm×2 mm) are stored at elevated temperatures at 80° C. The parameters measured are stickiness according to PV1306, durability via 3-point bending test until embrittlement and color deviation (gray scale and Delta E*) and gloss at 60°. 
     The injection molded plaques are also exposed to artificial weathering according to Volkswagen Norm PV1306 (Stickiness Test) (Xenon light, irradiance 40 W/m 2 © 300-400 nm, black panel temperature 80° C., relative humidity 20%+/−10%) and Volkswagen Norm PV3930 (Florida Test) (Xenon light, irradiance 60 W/m 2 © 300-400 nm, black panel temperature 65° C., relative humidity 35-45%+/−5%). The parameters measured are stickiness according to PV1306, color deviation (gray scale and Delta E*) and gloss at 60°. 
     The inventive examples IE11 and IE12 show superior performance.

     Preparation of the Tested Specimen: 
     The components of the formulation listed in Tables 7a, 7b, 7c, 8a, 8b, 9a and 9b are pre-mixed in a high-speed mixer. This mixture is compounded in a twin-screw extruder Berstorff® ZE 25×32D at 230° C. under N 2  blanket. The full formulation is then injection molded at 230° C. on an Engel HL65 injection molding machine. The injection molded plaques (68 mm×44 mm×2 mm) are stored at elevated temperatures at 140° C. The parameters measured are stickiness according to PV1306, durability via 3-point bending test until embrittlement and color deviation (gray scale and Delta E*) and gloss at 60°. 
     The injection molded plaques are also exposed to artificial weathering according to Volkswagen Norm PV1306 (Stickiness Test) (Xenon light, irradiance 40 W/m 2 @ 300-400 nm, black panel temperature 80° C., relative humidity 20%+/−10%) and Volkswagen Norm PV3930 (Florida Test) (Xenon light, irradiance 60 W/m 2 © 300-400 nm, black panel temperature 65° C., relative humidity 35-45%+/−5%). The parameters measured are stickiness according to PV1306, color deviation (gray scale and Delta E*) and gloss at 60°. 
     The inventive examples IE11 and IE12 show superior performance.

     Example 4: Aging of PET 
     Preparation of the Tested Specimen: 
     The components of the formulation listed in Tables 10a and 10b are pre-mixed in a high-speed mixer. This mixture is compounded in a twin-screw extruder Berstorff® ZE 25×32D at 260° C. under N 2  blanket. The full formulation is then injection molded at 230° C. on an Engel HL65 injection molding machine. The injection molded plaques (68 mm×44 mm×2 mm) are stored at elevated temperatures at 160° C. The parameters measured are stickiness according to PV1306, durability via 3-point bending test until embrittlement and color deviation (gray scale and Delta E*) and gloss at 60°. 
     The injection molded plaques are also exposed to artificial weathering according to Volkswagen Norm PV1306 (Stickiness Test) (Xenon light, irradiance 40 W/m 2 © 300-400 nm, black panel temperature 80° C., relative humidity 20%+/−10%) and Volkswagen Norm PV3930 (Florida Test) (Xenon light, irradiance 60 W/m 2 © 300-400 nm, black panel temperature 65° C., relative humidity 35-45%+/−5%). The parameters measured are stickiness according to PV1306, color deviation (gray scale and Delta E*) and gloss at 60°. 
     The inventive examples IE11 and IE12 show superior performance.

     Example 5: Aging of Polyethylene Film 
     Preparation of the Tested Specimen: 
     The components of the formulation listed in Table 11 are pre-mixed in a high-speed mixer. This mixture is compounded in a twin-screw extruder OMC 19×25D at 200° C. The full formulation is then extruded to cast films at 220° C. on a Collin E 30 M 30×25D cast film machine to 120 micron thick films. The films are exposed to artificial weathering according to DIN EN ISO 4892-2 Cycle 1 (Xenon light, Boro/Boro-filter, irradiance 0.5 W/m 2 © 340 nm, black panel temperature 65° C., relative humidity 65%+/−10%, 102 min wet/18 min dark cycle) and ASTM G154 Cycle 2 UV-B (Q-Panel, irradiance 0.78 W/m 2 © 313 nm, black panel temperature 70° C. in light, black panel temperature 50° C. dark). The parameters measured are time until carbonyl index increase 0.1 units and retained elongation.

     The components of the formulation listed in Table 13 are pre-mixed in a high-speed mixer. This mixture is compounded in a Leistritz 25 mm co-rotating extruder at 230° C. The received pellets are ground with 35 mesh Reduction Grinder. The full formulation is then rotomolded at max 240° C. on an LRM 1000 STP Rotomachinery. Plaques are cut out. The plaques are exposed to artificial weathering according to ASTM G-155A. Additional the migration out of the plaques into a food simulant is tested. The parameters measured are impact strength, color deviation (YI and Delta E*) and extraction into food simulant. 
     The inventive examples IE11 and IE12 show superior performance.
