Abstract
The invention provides a polyphenylene ether modified phenol-benzaldehyde multifunctional epoxy resin with formula (I) Their manufactured is following steps: polyphenylene ether 100 parts is dissolved in solvent, then phenol-benzaldehyde multifunctional epoxy resin 100˜450 parts and catalyst 0.01˜5 parts are added, stirred and mixed at 90˜180, for 1˜4 hour, to obtain formula (I) solution. Said product is formulated with compositions for laminate, having excellent electrical properties and heat resistance. The dielectric constant is 4.03(1 GHz), dissipation factor is 0.0046(1 GHz) and no delamination longer than 60 minutes dipping in 288soldering test after 2 hours pressure cooking test. Application is insulating materials for highly reliable electronic components such as EMC, PCB substrates, laminate and insulating plates.
