A polymer comprising structural units derived from a polycyclic dihydroxy
compound of Formula (I) wherein R.sup.1, R.sup.2 and R.sup.3 are
independently at each occurrence selected from the group consisting of a
cyano functionality, a halogen, an aliphatic functionality having 1 to 10
carbons, a cycloaliphatic functionality having 3 to 10 carbons, and an
aromatic functionality having 6 to 10 carbons; wherein each occurrence of
"n", "m", and "p" independently has a value of 0, 1, 2, 3, or 4; and
wherein the polymer is substantially linear.
