Desorption in Homopolymer Systems

The desorption (exit) of free radicals from polymer particles into the aqueous phase is an important kinetic process in emulsion polymerization. Smith and Ewart [4] included the desorption rate terms into the balance equation for N particles, defining the rate of radical desorption from the polymer particles containing n free radicals in Eq. 3 as kftiN . However, they did not give any [Pg.16]

Polymer particles contain at most one radical (zero-one system). [Pg.17]

An oligomeric radical with no more than s monomer units can desorb from and re-enter into a polymer particle with the same rate, irrespective of its chain length. [Pg.17]

Instantaneous termination takes place when another radical enters a particle already containing a radical. [Pg.17]

No distinction is made between radicals with or without an initiator fragment on its end. [Pg.17]
