Abstract:
A composition comprising a Group VIII metal and a polymeric phosphite composition whereinsaid polymeric phosphite composition is selected from the group consisting of polymer A, polymer B, and combinations thereof; said polymer A comprises repeat units derived from (1) a carbonyl compound, (2) a monomer, and (3) phosphochloridite; said polymer B comprises repeat units derived from (1) phosphorus trichloride, (2) a polyhydric alcohol, and (3) an aromatic diol; said carbonyl compound is selected from the group consisting of (R1O2C)m(OH)â€”Ar1â€”(OH)(CO2R1)m, (R1O2C)m(OH)â€”Ar2â€”A2â€”Ar2â€”(OH)(CO2R1)m, (R1O2C)m(OH)â€”Ar2â€”Ar2â€”(OH)(CO2R1)m, and combinations of two or more thereof; said monomer is selected from the group consisting of polyhydric alcohol, amine, and combinations thereof; said phosphochloridite has the formula ClP(Oâ€”Ar2â€”R2)2 in which the Ar2 groups are unlinked to each other, directly linked to each other, or linked to each other through group A2; each Ar1 is selected from the group consisting of phenylene group, biphenylene group, naphthylene group, binaphthylene group, and combinations of two or more thereof; each Ar2 is independently selected from the group consisting of phenylene group, naphthylene group, and combinations thereof; each A2 is independently selected from the group consisting of â€”C(R1)(R1)â€”, â€”Oâ€”, â€”N(R1)â€”, â€”Sâ€”, â€”S(O)2â€”, â€”S(O)â€”, and combinations of two or more thereof; each R1 is independently selected from the group consisting of hydrogen, C1 to C12 alkyl or cycloalkyl group, C6 to C20 aryl group, and combinations of two or more thereof; each R2 is independently selected from the group consisting of hydrogen, C1 to C12 alkyl or cycloalkyl group, acetal, ketal, â€”OR3, â€”CO2R3, C6 to C20 aryl group, F, Cl, â€”NO2, â€”SO3R3, â€”CN, perhaloalkyl, â€”S(O)R3, â€”S(O)2R3, â€”CHO, â€”C(O)R3, cyclic ether, â€”A1Z, and combinations of two or more thereof; Z is selected from the group consisting of â€”CO2R3, â€”CHO, â€”C(O)R3, â€”C(O)SR3, â€”SRâ€”C(O)N(R1)R1, â€”OC(O)R3, â€”OC(O)OR3, â€”N&boxH;C(R1)R1, â€”C(R1)&boxH;NR1, â€”C(R1)&boxH;Nâ€”Oâ€”R1, â€”P(O)(OR3)(OR3), â€”S(O)2R3, â€”S(O)R3, â€”C(O)OC(O)R3, â€”NR3CO2R3, â€”NR3C(O)N(R1)R1,F,Cl, â€”NO2, â€”SO3R3, perhaloalkyl, â€”CN, and combinations of two or more thereof; A1 is a C1 to C12 aklylene group; each R3 is independently selected from the group consisting of C1 to C12 alkyl or cycloalkyl group, C6 to C20 aryl group, and combinations thereof; and each m is independently a number in the range of from 1 to 2.
