A polymer comprising structural units derived from a polycyclic dihydroxy
compound of Formula (I) ##STR00001## 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.
