摘要:A process has been surprisingly discovered that can produce a high heat carbonate polymer (i.e., one with a Tg greater that 150° C.), without the drawbacks encountered in attempts to produce a high heat carbonate polymer. The process of the instant invention comprises the steps of: n (1) reacting an aromatic amine with a dihydric phenol to prepare an aminophenol; n (2) reacting an anhydride or dianhydride with the aminophenol to prepare a phenolic precursor; and n (3) reacting the phenolic precursor with a carbonate precursor to prepare a high heat carbonate polymer.

摘要:Provided is an epoxy compound that is useful as a novel epoxy resin monomer.　In the present invention, a novel epoxy resin monomer is provided by subjecting an α, β-unsaturated aldehyde or the like to epoxidation in order to obtain a 2,3-epoxy aldehyde, reducing said 2,3-epoxy aldehyde and thereby obtaining a 2,3-epoxy alcohol, and subjecting the result to an ether synthesis reaction. Examples of the epoxy compound include the epoxy compounds represented by formula (1-1-10), formula (1-1-28), formula (1-1-33), formula (1-1-34), formula (1-1-221), formula (1-1-241), formula (1-1-243), formula (1-1-249), formula (1-1-251), formula (1-1-259), formula (1-1-260), formula (1-1-263), formula (1-1-275), formula (1-2-1), formula (1-2-2), formula (1-3-2), formula (1-3-6), formula (1-4-9), formula (1-5-9), formula (1-5-19), and formula (1-5-20).
