| titleOfInvention | Imide-amide and urea-siloxane blocks containing thermostabile blockcopolymers |
| abstract | The present invention relates to new thermostable block copolymers comprising (imide-amide) and (urea-siloxane) blocks.n n n - étape (a) : préparation d'un oligomère à groupements N = C = O terminaux à partir d'un diisocyanate aromatique et d'un monoanhydride d'acide tricarboxylique aromatique, et - étape (b) : réaction dudit oligomère avec une diamine de formule :n dans laquelle : X représente :n R₁, R₂, R₃, R₄ et R₅ représentent chacun un radical hydrocarboné ; x est un nombre allant de 2 à 8 ; et la somme y + z est comprise entre 0 et 100. More precisely, these copolymers are obtained by linking the following two stages: step (a): preparation of an oligomer with N = C = O end groups from an aromatic diisocyanate and an aromatic tricarboxylic acid monoanhydride, and step (b): reaction of said oligomer with a diamine of formula: in which: X represents: R₁, R₂, R₃, R₄ and R₅ each represent a hydrocarbon radical; x is a number ranging from 2 to 8; and the sum y + z is between 0 and 100. n n n These copolymers are used for the production in particular of coating films. |
