To produce shaped bodies, from a mixt. of raw fibres and a bonding agent, the raw material is wettened with the required amount of water for the hydration of the bonding agent and then reduced to fibres while wet. The raw fibre material and the bonding agent are pref. ground together which reduces the material to fibres and mixes it with the bonding agent, or they are ground separately to be mixed...

A process for preparing a resorcinol copolymer, comprising at least one specific phenol with formaldehyde at a certain mole ratio to obtain a resol-type precondensate containing 1 to 30% of residual unreacted formaldehyde and then adding said resol-type precondensate to a mixture of an acid catalyst and at least one resorcinol to effect co-condensation. The obtained copolymer is useful for an adhe...
