Abstract

A polymer comprising structural units derived from a polycyclic dihydroxy compound of Formula (I)wherein R1, R2 and R3 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.
