AI Technical Summary
Existing polynatyl ester resins have high dielectric constants and dielectric losses at high frequencies, and their preparation process suffers from poor heat and mass transfer capabilities and thermo-oxidative degradation, making it difficult to meet the needs of future 6G communication.
A continuous polymerization method involving a three-stage gradient heating reaction and strong shear was adopted. By reacting p-acetoxybenzoic acid, 6-acetoxy-2-naphthoic acid, and raw material A under an inert atmosphere, followed by continuous polymerization under vacuum, a low molecular weight prepolymer was prepared and the molecular weight was increased to obtain a high molecular weight, fully aromatic polynaphthalene ester resin with excellent dielectric properties.
This study achieves excellent dielectric properties of polynatride resin, with reduced dielectric constant and dielectric loss, and a short production cycle, making it suitable for microelectronic devices.
