    摘要: Resol type phenol resins containing scarcely or no phenol mononucleus compounds (monomers) and phenol dinuclei compounds (dimers) and their methylolated derivatives and scarcely containing molecules having an apparent molecular weight of more than 2500 are produced by reacting phenol with formaldehyde in the presence of an alkaline catalyst in a molar ratio of 3.0 to 6.0 moles of formaldehyde and 0.05 to 2.0 moles of the alkaline catalyst per mole of phenol, neutralizing the reaction solution with an acid to pH 4.5 to 6.5 and precipitating the resulting product for separation.

    摘要: A vehicle hood panel is formed by bonding an outer panel and an inner panel to each other. Disposed along the outer peripheral edge of the inner panel is an outer peripheral portion to which a cushion member and hinges for attaching the hood panel to a vehicle are to be later fastened. Adhesive bonding surfaces which are to be bonded to the outer panel by mastic are disposed on the region surrounded by the outer peripheral portion, and a plurality of reinforcement beads are formed between the adhesive bonding surfaces. At least some of the adhesive bonding surfaces and/or reinforcement beads are bended so as to extend toward the hinges or the cushion member as seen in a plan view.
