A new class of branched dendrimeric macromolecules, is described essentially consisting of a polyvalent central nucleus and a series of polyoxaalkylene 'dendra'. Such molecules are characterized by the presence of at least one branch, attached either directly to the 'core' or to a 'dendron', which does not participate in the growth and which therefore differs from all the other functions of the macromolecule.

Selectively functionalizable desdendrimers

Branched, dendrimeric macromolecules having a central nucleus and a series of polyoxaalkylene chains that radiate from the nucleus and spread into the surrounding space branching a cascade fashion until the desired size results. Molecules formed in this manner are free of excessive functional crowding on their outer surfaces. Synthetic methods of preparing these molecules and their uses are described.

Binary-branched polyoxaalkylene macromolecules process for making them

A new class of branched dendrimeric macromolecules, is described essentially consisting of a polyvalent central nucleus and a series of polyoxaalkylene 'dendra'. Such molecules are characterized by the presense of at least one branch, attached either directly to the 'core' or to a 'dendron', which does not participate in the growth and which therefor differs from all the other functions of the macromolecule.

Branched, dendrimeric-type macromolecules composed essentially of a central nucleus and of a series of polyoxaalkyl chains that depart from said nucleus and spread into the surrounding space branching in a cascade fashion useful as carriers of drugs, contrast agents, etc.

Branced polyoxaalkyl macromolecules

The present invention concerns the use of dendrimeric-type branched macromolecules, comprising polyoxaalkylene chains, as catalysts or coadjuvants of phase transfer catalysis reactions.
