Abstract
Disclosed herein is a process for preparing a polymer comprising structural units derived from polycyclic dihydroxy compound having Formula (I), wherein Ris selected from the group consisting of a cyano functionality, a nitro functionality, an aliphatic functionality having 1 to 10 carbons, an aliphatic ester functionality having 2 to 10 carbons, a cycloaliphatic ester functionality having 4 to 10 carbons and an aromatic ester functionality having 4 to 10 carbons; Ris selected from the group consisting of a cyano functionality, a nitro functionality, an aliphatic ester functionality having 2 to 10 carbons, a cycloaliphatic ester functionality having 4 to 10 carbons and an aromatic ester functionality having 4 to 10 carbons; and each Rand R, at each occurrence, can be the same or different and are independently at each occurrence an aliphatic functionality having 1 to 10 carbons or a cycloaliphatic functionality having 3 to 10 carbons, 'n' is an integer having a value 0 to 4 and 'm' is an integer having a value 0 to 4. The process comprises subjecting a polycyclic dihydroxy compound of Formula (I) to polymerization.
