摘要
A resin blend that includes a copolymer of styrene and maleic anhydride (SMA), an epoxy resin (brominated, phosphonated, or bromine-free), and a multifunctional amine cross-linking agent is disclosed. The cross-linking agent generally contains at least two primary amino groups to promote formation of imide functionalities upon reaction with the anhydride moieties of the SMA copolymer. Particularly useful cross-linking agents include triazine-centered diamino and triamino compounds such as benzoguanamine, acetoguanamine, and melamine. The disclosed resin blend finds use as a polymer matrix in composite materials and as an impregnating resin in laminates. Compared to conventional SMA copolymer/epoxy resin blends, the disclosed resin exhibits lower dielectric constant and dissipation factor, as well as higher thermal and moisture resistance, making it especially useful in high-speed, low-loss printed wire board applications.
