Laminates prepared from resol-type phenol resins |
摘要 |
A new resol-type phenol resin is described which is obtained by heat-reacting isopropenylphenol oligomer as partial or whole phenol component of the resin with an aldehyde in the presence of a basic catalyst. Varnishes are obtained by adding a suitable vehicle to the resin. Laminates manufactured by impregnating a base with the phenol resin and heating the impregnated base to cure the resin are obtained with superior mechanical and electrical characteristics.
