The samples containing the instant compounds exhibit  good TPO/paint interaction properties as determined by the  criteria above.  Samples are tested to evaluate the TPO/paint interactions  as follows: In the initial adhesion test, a clear cellophane  adhesive tape is used to pull on a 3 mm cross hatched paint  surface or; in the humidity test, the painted plaques are  exposed for 240 hours at 38°  C. in an atmosphere having  98% relative humidity. The blister rating is tested by visual  observation according to  ASTM D  714.  2,2’-e thy lidene bis(2,4-di-te rt-bu ty lpheny 1) fluorop hos› phite and 2-butyl-2-ethylpropan-1,3-diyl 2,4,6-tri-tert› butylphenyl phosphite as well as the instant compounds of  also exhibit stability against the deleterious effects of actinic  light and thermal exposure.  Articles prepared according to Example 90 which addi› tionally contain an organophosphorus stabilizer selected  from the group consisting of tris(2,4-di-tert-butylphenyl)  phosphite, bis(2,4-di-tert-buty 1-6-methy lpheny 1) ethy 1  phosphite, 2,2’,2"-nitrilo[triethyl-tris -(3,3’, 5,5’-tetra-tert› butyl-1,1’-biphenyl-2,2’-diyl) phosphite ], tetrakis(2,4-di› buty lpheny l) 4,4’-biphenylenediphosphonite, tris  (nony lphenyl) phosphite, bis(2,4-di-tert-butylphenyl)  pentaerythrityl diphosphite,  The test specimens are painted with one-pack paint sys› tems and tested for TPO/paint interactions. Before painting,  the test specimens are first wiped with isopropanol and air  blasted to remove any dust. After a five minute flash, these  specimens are coated with the adhesion promoter, then the  base coat, and then optionally a clear coat. Typical film  thickness of these various coatings are 0.1-0.3 mils for the  adhesion promoter, 0.6-0.8 mils for the base coat, and  1.2-1.5 mils for the clear coat. After painting, the specimens  are cured in an over at 120°  C. for 30 minutes.  Molded test specimens are prepared by injection molding  thermoplastic olefin  (TPO)  pellets containing the instant  compounds, pigments and other coadditives as described in  Example 77.  Articles prepared according to Example 90 which addi› tionally contain a hindered phenolic antioxidant selected  from the group consisting of neopentanetetrayl tetrakis(3,5- di-tert-buty 1-4-hydroxyhydrocinnamate, octadecy 1 3,5-di› tert-buty l-4-hydroxyhydrocinnamate, 1,3,5-trimethyl-2,4,6- tris(3,5,-di-tert-butyl-4-hydroxybenzyl)benzene, 1,2-bis(3,  5-di-tert-bu ty 1-4-h ydroxy h ydrocinnamoy 1 )hydrazine,  calcium [bis(monoethyl 3,5-ditert-butyl-4-hydroxybenzyl)› phosphonate ], 1,3,5-tris(3,5-di-tert-butyl-4-hydroxybenzyl)  isocyanurate and 1,3,5-tris(3-hydroxy-4-tert-buty 1-2,6- dimethylbenzyl) isocyanurate, as well as the instant com› pounds also exhibit stability against the deleterious effects of  actinic light and thermal exposure.  When tested for light stabilizing activity as described in  Example 82, the films containing the instant compounds  exhibit good stabilization.  Film grade polyethylene is compounded and blown into  film at 200°  C. as described in Example 82 using a  DOLCI  film line. In addition to the instant compounds, selected  flame retardants are included in the formulation. The flame  retardants are tris(3-bromo-2,2-bis(bromomethyl)propyl)  phosphate, decabromodiphenyl oxide, ethylene bis- (tetrabromophthalimide ), or ethylene bis-( dibromo› norbomanedicarboximide ).  Articles prepared according to Example 90 which addi› tionally contain selected organic pigments as well as the  instant compounds also exhibit stability against the delete› rious effects of actinic light and thermal exposure.  The samples including the instant hindered amines exhibit  good light stabilizing activity.  Molded test specimens are prepared by injection molding  thermoplastic olefin (TPO) pellets as described in Example  76. In addition to the instant compounds, selected flame  retardants are also included in the test specimens. The flame  retardants are tris(3-bromo-2,2-bis(bromomethyl)propyl)  phosphate, decabromodiphenyl oxide, ethylene bis› (tetrabromophthalimide ), or ethylene bis-( dibromo› norbomanedicarboximide ).  The materials containing the instant compounds exhibit  stability against deleterious effects of UV light and thermal  exposure.  The pelletized fully formulated resin is then processed  into a useful article such as blown or cast extrusion into film;  injection molded into a molded article; thermoformed into  molded articles; extruded into wire and cable housing; or  rotational molded into hollow articles.  of styrene with butadiene or isoprene and/or ethylene› cobutylene such as  SES, SEES  and  SIS,  are dry blended  with the instant compounds and melt compounded into  pellets. Typical formulations contain the instant compounds  at levels from 0.05% to 2.0%, a metal stearate such as  calcium stearate at 0.05% to 0.5%, pigments from 0% to 5%,  UV absorbers at levels of 0.05% to 2.0%, phosphites at  0.0%-0.1 %, phenolic antioxidants at 0.0%-1.25%,  N,N› dialkylhydroxylamine at 0.0%-0.1 %, and optionally other  hindered amine stabilizers at levels of 0.0% to 2.0%.  The test samples containing the instant compounds  exhibit good light stabilization properties.  Test plaques are mounted in metal frames and exposed in  an Atlas Ci65 Xenon Arc Weather-Ometer with intermittent  light/dark cycles and water spray following the  ASTM  G26  test procedure. Specimens are tested at periodic intervals for  changes in tensile properties. Failure in this test is deter- mined by the observation of the loss of tensile properties.  The longer it takes for the loss in properties to occur, the  more effective is the stabilizer system.
