Title
(EN) A DENDRITIC MACROMOLECULE AND A PROCESS THEREOF
(FR) MACROMOLÉCULE DENDRITIQUE ET PROCÉDÉ POUR LA PRÉPARER
Abstract
(EN)
The present invention is in relation to a dendritic molecule having symmetrically sited branches having four or more generations of dendrimers wherein the branch points are tertiary amines linked together with oxygen atom of ether and the heteroatoms are separated by a substituted or non-substituted linear three methylene linker. In addition the invention also provides a process to prepare such dendritic macromolecules.
(FR)
La présente invention concerne une molécule dendritique comportant des ramifications sur des sites symétriques ayant quatre générations ou plus de dendrimères, dans lesquels les points de ramification sont des amines tertiaires liées ensemble par un atome d'oxygène de groupe éther et les hétéroatomes sont séparés par un lieur de trois méthylènes linéaire non substitué. En outre, l'invention concerne aussi un procédé pour préparer ces macromolécules dendritiques.
