Abstract:
1. A process for preparing a polymer, comprising reacting acetone with a compound of Formula (III) in the presence of a first catalyst to produce dibenzalacetone of Formula (IV) reacting the dibenzalacetone of Formula (IV) in the presence of a second catalyst with a compound of Formula (V) to produce a compound of Formula (VI) reacting the compound of Formula (VI) with a compound of Formula (VII) in the presence of an acid catalyst and a promoter to produce a compound of Formula (I), wherein R 1 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; R 2 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 each R 3 and R 4 , 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; and polymerizing the compound of Formula (I).
