Abstract

Moulded phenol-methylene condensation products are prepared according to the process described in Specification 146,159, employing as a constituent of the binder a fusible condensation product containing two and a third to three and a half (preferably two and a half) phenolic groups to each methylene group. The proportions of the methylene compound which comprises the other constituent of the binder are then selected to give to the binder as a whole one methylene group to each phenolic group present. A slowly volatile hydrocarbon solvent such as creosote oil may be incorporated in the mixture. Specification 9291/14 also is referred to.
