Title: Production of oil-modified phenolic resin
Inventor: SHIMOOKE RIYOUKO
IPC: H05K1/03
Filed: 1989-12-15
Abstract: PURPOSE:To increase the degree of addition reaction of a phenol with tung oil in producing a tung oil-modified phenolic resin by carrying out the reaction in the presence of methanol and a catalyst comprising p-toluenesulfonic acid.
