BACKGROUND OF THE INVENTION

method for the deactivation of metal catalyst residues in polyester and Polyester-polycarbonate compositions are known in the art; however, it is desirable to find improved methods of deactivating such residues. It is also desirable To find a method for deactivating catalyst residues, which Compositions with greater hydrolytic stability provide that for process equipment less detrimental are, better color and less color variation from approach to Provide an approach.

It It is known in the art that certain phosphorus-containing compounds for the Deactivation of metal catalyst residues are useful. It will be for example to U.S.. Patents 3,218,372 (Okamura et al.), 4,532,290 (Jaquiss et al.), 4,088,709 (Seymour et al.), 4,401,804 (Wooten et al.), 5,922,816 (Hamilton) and European Patents 0,543,125 (Van Helmond), 0 294 862 (Verhoeven), 0 295 730 (Verhoeven). Examples for such Phosphorus-containing compounds include phosphoric acid, certain organic phosphorus compounds, such as distearyl pentaerythritol diphosphite, mono-, di- and trihydrogen phosphate compounds or Di- and triester phosphate compounds, phosphite compounds, certain inorganic phosphorus compounds, such as monosodium phosphate, zinc or calcium phosphate, poly (ethylene) hydrogen phosphate, Phosphites and phosphates in combination with elemental sulfur silyl phosphates, phosphorus compounds used in Combinations with metal sulfides or metal sulfates can be used. U.S. U.S. Patent 4,452,933 (Russell) discloses the use of Hydroxy- or amino-substituted carboxylic acids, such as methyl salicylate, maleic acid, Glycine or dibutyl tartrate to inactivate metal catalyst residues. U.S. U.S. Patent 4,452,932 (Brunelle) discloses the use of dehydroacetic and a hydroxy aromatic compound, such as o-hydroxybenzophenone, for the Inactivation of metal catalyst residues. It is also known certain polyols, such as mannitol, can be used to to improve the color of polyester and polycarbonate blends, as in the European Patent 0 272 417 (Nelson).

The U.S. U.S. Patent 4,619,956 discloses the combination of the hindered ones Amine light stabilizers (HALS) 2,2,6,6-tetraalkylpiperidines and / or their addition salts with triazine ultraviolet absorbers for the stabilization of thermosetting Acrylic and alkyd coating agents. U.S. Patent 5,714,530 reveals the usefulness the combination of non-polymeric 2,2,6,6-tetralkylpiperidine-HALS salts and / or their Acid addition salts with triazine ultraviolet adsorbents for the Stabilization of certain polymer compositions. U.S. patent No. 6,051,164 discloses the use of a polymer stabilization system which is about 50 to about 5000 ppm of at least one ortho-hydroxyltrisaryltriazine light absorber and about 500 ppm to about 1.25 percent of at least one oligomer, polymeric or higher molecular weight HALS having a molecular weight of at least 500, wherein the weight ratio from HALS to triazine light absorber about 3: 1 to about 20: 1 is.

Certain of these phosphorus-containing compounds, for example phosphoric acid, phosphoric (III) acid and polyphosphoric acid, may react with the process equipment, producing a dark colored polymer and leading to the formation of black spots or particles. It is believed that the dark color is due to the corrosion of the process equipment. The addition of strong acids to the polymer compositions also reduces hydrolytic stability as a result of acid-catalyzed hydrolysis. In addition, phosphite antioxidants can be hydrolyzed to acidic species, thereby corroborating the process equipment or reducing the hydrolytic stability of the polymer composition. It is desirable to provide an additive or mixture of additives that are used to deactivate metal catalyst residues and other metal contaminants and thereby improve the color of polyester-polycarbonate compositions leading to less corrosion of process equipment and suppress transesterification.

EXAMPLES 1-12 AND COMPARATIVE EXAMPLES 1 AND 2

The hindered amine light stabilizer Chimassorb 944 and phosphoric (III) acid of Examples 1-12 of Table I were triturated together using a mortar and pestle until a fine powder was obtained. Varying amounts of the resulting amine-phosphoric (III) acid salt were mixed with the polymers consisting of 350 g polyester and 350 g polycarbonate as described above. It is believed that the Chimassorb 944 is a polymeric hindered amine generally corresponding to the above-identified amine formula (12) wherein R ₆ = R ₇ = R ₈ = R ₉ = methyl; R _{10 is} hydrogen; L _{1 is} hexamethylene; R _{3 is} hydrogen; and R _{4 is} a branched octyl group. Table I shows the b * value as measured on pellets measured from the weight based 50/50 blend of polyester and polycarbonate containing various concentrations of Chimassorb 944, phosphoric (III) acid and water , Salts made from Chimassorb 944 and phosphoric (III) acid may contain varying ratios of phosphoric (III) acid to Chimassorb 944 to improve catalyst deactivating ability and improve the color of polyester-polycarbonate compositions. Table I gives the amounts of Chimassorb 944 and phosphoric (III) acid in grams and the amount of water is in milligrams. TABLE I

Lower amounts of salt (Examples 1-4) allowed for an equivalent reduction of the b * value without a significant impact on the polycarbonate molecular weight to have. The addition of a small amount of water (Examples 9-12) decreased the b * value in large Measure with only a slight negative impact on the polycarbonate molecular weight compared to the examples with equivalent amounts of salt. One Salt containing about 0.02 to 0.3% by weight of phosphoric (III) acid and 0.05 to about 0.5 weight percent Chimassorb 944 a suitable reduction of pellet b * color, without significantly the polycarbonate molecular weight to reduce.

The compositions were extruded and evaluated as described above. The results are shown in Table III. The polymer blend of the examples of Table III consisted of 175 grams of polyester and 175 grams of polycarbonate. The values reported for Tinuvin 770 and phosphoric (phos-) acid are concentrations in mg and (weight percent) in the polymer blend.

The data reported in Table III show that the hindered amine phosphorus (III) acid salts Tinuvin 770 were effective to suppress transesterification and to improve the pellet b * color. The added weight percent of phosphoric (III) acid was determined by changing the molar ratio of phosphoric (III) acid to the number of nitrogen atoms in Tinuvin 770. The data in Table III show a good balance of color of the composition and the polycarbonate molecular weight (Mw) retention can be obtained by using a 1: 1 molar ratio of Tinuvin 770 and phosphoric (III) acid using 0, 1 weight percent salt used. At a concentration of 0.05% by weight loading, the molar ratio of phosphoric (III) acid to Tinuvin 770 can be increased to 2.0. It is apparent from these data that the Tinuvin 770 salt is quite effective in improving the color of the polyester-polycarbonate blends. The Tinuvin 770 salt is also effective to reduce the degree of transesterification that occurs between the polyester and the polycarbonate during melt processing.

EXAMPLES 26-45 AND COMPARATIVE EXAMPLES 5-8

The procedure of Examples 17-25 was repeated using varying amounts of hindered amine light stabilizers Lowilite 62, Lowilite 76 and Chimassorb 119, and phosphoric (III) acid to produce a variety of hindered amine phosphoric (III) acid salts to create. Lowilite 62 is a hindered amine light stabilizer, which is believed to generally correspond to the compounds of the above-identified amine formula (20) in which R _{1 is} hydrogen; R ₂ = R ₆ = R ₇ = R ₈ = R ₉ = methyl; L _{2 is} ethylene; and Y _{1 stands} for -OCO. Lowilite 76 is a hindered amine light stabilizer, which is believed to generally correspond to the compounds of the abovementioned amine formula (7) wherein R ₆ = R ₇ = R ₈ = R ₉ = R ₁₀ = methyl; Y _{2 is} -O-; and L _{1 is} -CO- (CH ₂ ) ₈ -CO-. The chemical name for Chimassorb 119 ^® is 1,3,5-triazine-2,4,6-triamine, N, N'-1,2-ethanediylbis [[[4,6-bis [butyl-1,2,2 , 6,6-pentamethyl-4-piperidinyl) amino] -1,3,5-triazin-2-yl] amino] -3,1-propanediyl]] to [N, N "-di-butyl N, N" - bis (1,2,2,6,6-pentamethyl-4-piperidinyl) -.

The values given for Lowilite 62, Lowilite 76, Chimassorb 119 (Chimab 119) and phosphoric (III) acid (phosphonic acid) are concentrations in mg in the polymer blend.

The data presented in Table IV show that the phosphoric (III) acid salts hindered Amine light stabilizers are effective to improve the pellet b * color of polyester-polycarbonate blends as compared to blends containing no stabilizer. In Examples 26-45, several phosphoric (III) acid salt compositions were evaluated at concentrations of 0.05% and / or 0.1% by weight. It will be appreciated that the pellet b * color is greatly affected by the salt composition that is chosen and can be optimized for any hindered amine light stabilizer or other basic organic compound used. Comparing the data of Table III with the data of Table IV, it is clear that the phosphoric (III) acid salts of Tinuvin 770 are more effective at improving pellet b * color. The phosphoric (III) acid salts of Tinuvin 770, Lowilite 62, Lowilite 76 and Chimassorb 119 did not produce haze in any of the polyester-polycarbonate alloys that were evaluated.

Generally takes the required amount of salt to make an acceptable color and To obtain molecular weight properties, as the ratio of the Moles of phosphoric (III) acid to the mole basic nitrogen atoms in the hindered amine light stabilizers one approaches. When more than one mole of phosphoric acid per mole of basic nitrogen atoms used in the basic organic compound is something non-salted phosphoric (III) acid present and can lead to corrosion of process equipment.
