Polymers, polymer compositions and method of preparation

摘要

A polymer comprises structural units derived from a polycyclic dihydroxy compound of Formula (I) wherein R¹ is 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; R² is 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 R³ and R⁴ are independently at each occurrence a hydrogen, an aliphatic functionality having 1 to 10 carbons or a cycloaliphatic functionality having 3 to 10 carbons.
