, (2008/06/13)
A method of synthesizing multitier cascade polymers and the polymers made thereby are formed by reacting at least one tier of a polymer with a functionalized isocyanate having the following formula: with R being selected from the group including: with R' being selected from the group consisting of alkyl, cycloalkyl, aryl, heteroaryl- polycycloalkyl, adamantyl, n=0-10; with R' being selected from the group consisting of alkyl (c-1 to C(20), cycloalkyl (C-3 to C-10), aryl heteroaryl, polycycloalkyl, adamantyl, n=0-10; and with n=0-10, R" being selected from the group consisting of alkyl, cycloalkyl, aryl heteroaryl ester functionality, and a sulphur or a silicon atom bearing substituents selected from the group including: STR1 wherein R"' is alkyl (C-1 to C-20), cycloalkyl (C-3-C-10), aryl, heteroaryl, polycycloalkyl, adamantyl.
