Claims
- 1. A polymer prepared from a tris-[1,1,1-(4-hydroxyphenyl)] toluene described by formula as follows: ##STR2## wherein R is independently an inert substituent or an aliphatic or aromatic group, two or more R's are optionally joined to form cycloaliphatic or aromatic groups, and y is an integer of from 0 to 5; which has a mole ratio of isomers in which the hydroxy aromatic rings are bonded at the para position to those isomers in which the hydroxy aromatic rings are bonded at the ortho position of at least about 60:40.
- 2. The polymer of claim 1 wherein, in the tris-[1,1,1-(4-hydroxyphenyl)] toluene used in preparation thereof, R is an aliphatic group.

- 14. The polymer of claim 2 wherein the tris-[1,1,1-(4-hydroxyphenyl)] toluene used in preparation thereof has a mole ratio of para isomers to ortho isomers of at least about 90:10.
- 15. The polymer of claim 3 wherein the tris-[1,1,1-(4-hydroxyphenyl)] toluene used in preparation thereof has a mole ratio of para isomers to ortho isomers of at least about 75:25.
- 16. The polymer of claim 3 wherein the tris-[1,1,1-(4-hydroxyphenyl)] toluene used in preparation thereof has a mole ratio of para isomers to ortho isomers of at least about 90:10.
- 17. The polymer of claim 5 wherein the tris-[1,1,1-(4-hydroxyphenyl)] toluene used in preparation thereof has a mole ratio of para isomers to ortho isomers of at least about 75:25.
- 18. The polymer of claim 5 wherein the tris-[1,1,1-(4-hydroxyphenyl)] toluene used in preparation thereof has a mole ratio of para isomers to ortho isomers of at least about 90:10.
- 19. The polymer of claim 8 wherein, in the tris-[1,1,1-(4-hydroxyphenyl)] toluene used in preparation thereof, R is hydrogen, and the mole ratio of para isomers to ortho isomers is at least about 75:25.
- 20. The polymer of claim 8 wherein, in the tris-[1,1,1-(4-hydroxyphenyl)] toluene used in preparation thereof, R is hydrogen, and the mole ratio of para isomers to ortho isomers is at least about 90:10.
