Process for manufacture of amino formaldehyde resin |
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 DEG 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.
