摘要：
The phenolic resin synthesized from phenol and formaldehyde in the presence of a tertiary amine catalyst was chemically modified with a small amount of aniline derivative to produce a higher molecular weight, modified phenolic resin. The resulting resin was used as the curing agent of epoxy resin to produce the epoxide woven glass fabric laminated sheet. The insulation resistance of the laminated sheet after immersion in water is greater than 1011Ω, and other properties are similar to those of EP GC201 (IEC 893-3-2). The molecular weight distribution and structural feature of the modified phenolic resin were studied by means of gel permeation chromatography (GPC), infrared spectroscopy (IR) and proton magnetic resonance (1H-NMR) analytical techniques.
