Abstract

Compositions are provided that can include R F (R T ) n Q, and/or R Cl (R T ) n H. The R F group can have four fluorine atoms, the R T group can include a C-2 group having a pendant —CF 3 group, n can be at least 1, the R 1 group can include a carbon atom, the R Cl group can be —CCl 3 , and the Q group can include one or more atoms of the periodic table of elements. Telomerization processes are also provided.

Claims (21)

1 - 17 . (canceled)

18 . A telomerization process comprising exposing at least one CF 3 -comprising taxogen to a fluorine-comprising telogen to produce a telomer, wherein the fluorine-comprising telogen comprises at least two fluorine atoms.

19 . The process of claim 18 wherein the CF 3 -comprising taxogen is pentaluoropropene.

20 . The process of claim 18 wherein the fluorine-comprising telogen is (CF 3 ) 2 CFl.

21 . The process of claim 18 wherein the exposing the CF 3 -comprising taxogen to the fluorine-comprising telogen is in the presence of an initiator.

22 . The process of claim 21 wherein the initiator comprises a peroxide.

23 . The process of claim 22 wherein the peroxide comprises di-tert-butyl peroxide.

24 . The process of claim 22 wherein the exposing occurs within a reactor and the initiator and telogen are provided to the reactor, a mole ratio of the initiator to the telogen being between about 0.001 and about 0.05.

25 . The process of claim 24 wherein the mole ratio of the initiator to the telogen is between about 0.01 and about 0.03.

26 . The process of claim 19 wherein the exposing occurs within a reactor, a temperature within the reactor during the exposing being from about 130° C. to about 150° C.

27 . The process of claim 18 wherein:

the CF 3 -comprising taxogen is pentafluoropropene; and

the telomer comprises

wherein:

the R F group comprises at least two fluorine atoms;

n is at least 1; and

the Q group comprises one or more atoms of the periodic table of elements.

28 . The process of claim 18 wherein:

the CF 3 -comprising taxogen is pentafluoropropene;

the fluorine-comprising telogen is (CF 3 ) 2 CFl; and

a mole ratio of the taxogen to the telogen is from about 2:1 to about 4:1.
