  • T-butyl cascade polymers
    Publication number: 20070142663
    Abstract: A method for forming cascade polymers specifically utilizing the amine monomer of the formula The monomer is made by initially reacting nitromethane and CH2?CHCO2-TBu by nucleophilic addition to form the triester nitrotrialkanoate of the formula and then reducing the nitrosubstituent to afford the said amine monomer.
    Type: Application

  • Detection and functionalization of dendrimers
    Publication number: 20050008571
    Abstract: A method of detecting unreacted termini within a dendritic structure is achieved by exposing a dendrimer to a single generating compound capable of bonding to and tagging a deprotected but uncoupled termini. A signal generated by the signal generating compound to an otherwise uncoupled termini provides detection of the unreacted termini.

  • Unimolecular micelles and method of making the same
    Patent number: 5154853
    Abstract: In accordance with the present invention there is provided a method of making a cascade polymer including the steps of alkylating the branches of a multi-branch core alkyne building block including multiple ether side chains and simultaneously reducing the alkyne triple bonds and deprotecting to form a multi-hydroxyl terminated, multi-branched all alkyl polymer. The inventive method results in the formation of a unimolecular micelle consisting essentially of alkyl carbon.
