Slow monomer-addition strategy

NHS)-ester of lysine dihydrochloride in the presence of a polyfiinctional core, using the slow monomer addition strategy. A self-evident method for preparing hh poly(lysine) by direct self-condensation was reported more recendy by Klok and co-workers. ... 

Different synthetic strategies have been employed for the preparation of the pure organic hyperbranched polymers [23-25]. The most commonly adopted approach is self-condensation of AB -type monomers with n > 2 [26-29]. This type of polymerization can be carried out in a concurrent mode or by slow addition of the monomer or even in the presence of a core molecule of By (/ > 3), which allows various structural control over the growing polymer [30-32]. Another approach is copolymerizations of A monomers with B comonomers (n > 3) [33-35]. However, the stoichiometric requirements between the pairs of the functional comonomers...
