摘要：
Halogen-free epoxy resins that arise from the addition of an epoxy component to a phenol component with base catalysis are disclosed, whereby the molar mass can be adjusted by means of the molar ratios of the initial materials. The resulting resins can be used in the field of electronics, both as molding compounds and as circuit board materials and adhesives.
