Claims
- 1. An oligomer comprising at least 10 mole %, based on the total number of moles of aryl hydroxide units of said oligomer, repeat units of the formula ##STR9## wherein M.sup.+ is a monovalent metal cation; and wherein a=1 or 2 and R is C(R.sub.f).sub.3, with each R.sub.f group being independently selected from the group consisting of Fluorine or a perfluoroalkyl group; or wherein a=0, 1 or 2 and R is ##STR10## wherein each R.sub.f group is independently selected from the group consisting of Fluorine (F) or a perfluoroalkyl group;
- b=0, 1 or 2; and
- a+b=0, 1 or 2; with the proviso that
- a+b=1 or 2 for at least about half of said repeat units in said oligomer.
- 2. A stainblocker comprising the oligomer of claim 1.
- 3. A nylon carpet fiber including a coating applied thereto, said coating comprising about 0.1% to about 1.0%, based on the weight of said fiber, of the oligomer of claim 1.
- 4. An oligomer comprising at least 10 mole %, based on the total number of moles of aryl hydroxide units in said oligomer, repeat units of the formula: ##STR11## wherein M.sup.+ is a monovalent metal cation, and a=0, 1 or 2; b=0, 1 or 2; and a+b=0, 1 or 2; with the proviso that a+b=1 or 2 for at least about half of the subject units in the oligomer.
- 5. The oligomer of claim 4 wherein a+b=1 for about 45% to 55% of said repeat units; a+b=2 for up to 12% of said repeat units; and a+b=0 for about 35% to 40% of said repeat units, based on the total number of said repeat units in said oligomer.
- 6. The oligomer of claim 4 further including repeat units of the formula ##STR12## wherein c=0, 1 or 2; d=0, 1 or 2; and c+d=0, 1 or 2.
- 7. The oligomer of claim 4 wherein a+b=0 for about 38% of said repeat units; a+b=1 for about 50% of said repeat units; and a+b=2 for about 12% of said repeat units, based on the total number of said repeat units in said oligomer.
