摘要： A method for the manufacture of amino-formaldehyde resins of low water content. Amino compound and formaldehyde or paraformaldehyde are reacted at a temperature about 60.degree. C. in the liquid phase, the liquid phase being ensured by a reactive modifier. The reactive modifier is a compound which is capable of taking part in the reaction, and also capable of modifying the mixture of reactants to be liquid at the temperature at which the reaction is to be carried out.

摘要： A method of making a cured foamed amino formaldehyde product utilizes an amino formaldehyde precondensate of water content below 20% by weight in order to obtain a less brittle product. A liquid foamable composition is made by dispersing a curing catalyst and a blowing agent in the precondensate and the composition is heated to cause the blowing agent to form a foam and the precondensate to cure.

摘要： A vehicle deceleration bed comprises two portions of a cured non-resilient aminoplast resin foam material, the density and/or the compressive strength of the foam in one portion being different from that of the other portion. Preferably the portions are arranged in layers and in the case of an aircraft deceleration bed, the lowermost layer is the strongest, each such successive layer being of progressively lower strength.
