摘要：Method for the manufacture of a colourless or light-coloured phenolic polymernetwork using upon curing a phenolic resin emulsion and/or dispersion, in which analdehyde, a phenolic compound and an alkaline catalyst are allowed to react at a
temperature of 40-(100 DEG C until a desired degree of condensation is achieved, and thepH of the resin is adjusted to a value below 9 using an acid in the presence of a surfaceactive agent or a mixture of surface active agents at a temperature below the boilingpoint and a phenolic resin emulsion and/or dispersion is obtained and used as a precursorto give a colourless or light-coloured polymer network when cured. The phenolic resinemulsion and/or dispersion may optionally be spray-dried.
