Abstract
PURPOSE: To prepare a phenolic resin for laminated sheets having excellent electrical characteristics and punchability, by reacting a phenolic compound with an olefin-terminated compound in the presence of an acid catalyst, further reacting the product with formaldehyde.
CONSTITUTION: A phenolic resin for laminated sheets is prepared by reacting a phenolic compound with an olefin-terminated compound of ≥12C, e.g. DIALENE- 124, 168, 208 or 30 (trade name of Mitsubishi Kasei Kogyo KK), in the presence of an acid catalyst, followed by converting the product to the resol type by reacting with formaldehyde. Laminated sheets are prepared from the prepreg obtained by impregnating papers, etc. with the varnish provided by dissolving the above resin in an organic solvent
