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.

A method of making a cascade polymer includes the steps of:
- alkylating the branches of a multi-branched core alkyl compound with a terminal alkyne building block including multiple ethereal side chains, and simultaneously reducing the alkyne triple bonds and deprotecting to form a multihydroxyl terminated multi-branched all alkyl polymer.
An unimolecular micelle consisting essentially of a carbon core atom and essentially all alkyl arms extending therefrom.
A unimolecular micelle having the formula ##STR6## wherein R.sub.1 is an alkyl having C3 to C20, R.sub.2 is an alkyl having C3 to C20, R.sub.3 is selected from the group consisting of --CONH.sub.2, --COC1, CHO, --CN, --CO.sub.2 R.sub.4, --COR.sub.4, and R.sub.4 is selected from the group consisting of H, alkyl, alkaryl, aryl, ammonium, sulfonium phosphonium and metal salt.
A unimolecular micelle having the formula ##STR7## wherein R.sub.1 is a perfluoroalkyl having C3-C20, R.sub.2 is a perfluoroalkyl having C.sub.3 to C.sub.2-, R.sub.3 is selected from the group consisting of F, CF.sub.3, CONH.sub.2, COC1, CHO, CN, CO.sub.2 R.sub.4, and R.sub.4 is selected from the group consisting of F, CF.sub.3 perfluoroalkyl, perfluoroalkaryl, perfluoroaryl ammonium, sulfonium, phosphonium and metal salt.
