The invention relates to melamine-formaldehyde condensates with thermoplastic properties that can be produced from formaldehyde and melamine derivatives, where in at least one of the melamine derivatives organic radicals R have been used to substitute at least four of the total of six hydrogen atoms of the three melamine amino groups, and where the organic radicals R are mutually identical or different. The invention also relates to a process for production of the melamine-formaldehyde condensates, use thereof, and an analytical method for determining the constitution of the melamine-formaldehyde condensates.
L'invention concerne un produit de condensation mélamine-formaldéhyde présentant des propriétés thermoplastiques, pouvant être obtenu à partir de formaldéhyde et de dérivés de mélamine, au moins quatre des six atomes d'hydrogène des trois groupements amino de la mélamine d'au moins un des dérivés de mélamine étant substitués par des radicaux organiques R, les radicaux organiques R étant identiques ou différents les uns des autres. L'invention concerne également un procédé de fabrication du produit de condensation mélamine-formaldéhyde, son utilisation, ainsi qu'un procédé analytique de détermination de la composition du produit de condensation mélamine-formaldéhyde.
