Patent ID: 8445016

Claim:
A grafted polymer having the formula: wherein [OLIGO] is an oligomeric polymeric segment; [LINKA] is a first coupling segment linking at least two [OLIGO] groups to form (([OLIGO]-[LINKA]) a)-[OLIGO])) having a theoretical molecular weight of less than 15,000 Da; T is a terminal group; F T is a polyfluoroorgano group; [MRF] is a polyolefin; [INI] is a functional group having the capacity to initiate ATRP, atom transfer radical addition (ATRA), or atom transfer radical cyclization (ATRC); [LINKB] is a second coupling segment linking (([OLIGO]-[LINKA])a)-[OLIGO])) to F T , to T, and/or to [LINKC]; [LINKC] is a third coupling segment linking [LINKB] to [INI] or, in the absence of [INI], [LINKC] is a dendron of n generations; [Active Agent] is one or more active agents, and wherein the line between [Active Agent] and [MRF] in the formula represents an interaction that is a covalent bond or a non-covalent interaction; a and d are integers greater than 0; n is an integer from 1 to 150; p is an integer from 1 to 20; m is an integer from 1 to 20; y is an integer from 1 to 20; w is an integer from 1 to 20; and with the provisos that m≦n; and w≦y.
