Properties of 1,2-Polybutadine Copolymers Containing N,N-Diphenylacrylamide Groups

Abstract

Since the advancement of generative AI requires highly integrated multi-layered GPU, a large electric field is generated in copper-clad laminate (CCL) which reach high temperature. Therefore, low dielectric constants, high glass transition temperatures (Tg), and low coefficients of thermal expansion (CTE) are required for CCL resin layers. However, the pursuit of these properties is a trade-off, and the development of useful materials has been required. It has been reported that 1,2-polybutadiene (PB) which includes 1,2-vinyl units produced by living anionic polymerization has excellent low dielectric properties. In this study, we synthesized modified 1,2-PB block copolymers with enhanced thermal resistance using this method.
