      <text>Polymer prepared by polycondensation of an amino component such as amine or amide with an aldehyde, or by curing reactive oligomers prepared from an amino component and an aldehyde.</text>
      <notes>
        <item>Formaldehyde is commonly used as the aldehyde and (a) melamine or (b) urea as the amino component. The resulting polymer is named (a) melamine polymer or melamineformaldehyde polymer, (b) urea polymer or urea-formaldehyde polymer.</item>
        <item>A mixture of the reactive oligomers prepared by the condensation of an amino component with an aldehyde is, in a public (popular) use and technological practice, usually referred to as an amino resin, e.g., melamine-formaldehyde resin or urea-formaldehyde resin. Examples of the oligomers present in melamine-formaldehyde and ureaformaldehyde resins are: </item>
        <item>Use of the term "resin" for cured reactive oligomers is discouraged; the cured resin should be named as an amino polymer.</item>
        <item>An amino polymer is usually a network polymer. To form the polymer, polycondensation takes place at the hydroxymethyl groups of an amino resin. Examples of the network-structure motifs of that form are: </item>
        <item>Melamine polymers can be regarded as a subclass of polytriazines.</item>
