Author: B. VoitThis can be attributed to the short lifetime of the active growing polymer chain ( ~ s ) and the shift of comonomer feed by faster incorporation of the low molecular weight comonomer , as indicated by the reactivity ratio of 1 / IMMA ...
Author: Bruno AmeduriThe high addition polymerization reactivity of fluorinated vinyl compounds has been demonstrated under anionic conditions to afford facile methods for the formation of novel fluorinated polymers. The anionic addition polymerization of a ...
Author: Timothy P. LodgeThe copolymerization equation relates the instantaneous mole fraction of monomers incorporated into polymer to the instantaneous composition of the feedstock via the reactivity ratios. Different classes of behavior may be assigned based ...
Author: Graeme MoadNumerical approaches for estimating reactivity ratios by solution of the integrated rate equation have been describedm'126 Potential difficulties associated with the application of these methods based on the integrated form of the ...
Author: Ferdinand RodriguezA growing polymer chain's reactivity is determined solely by the last monomer unit added. This reactivity is independent of the molecular weight. 3. The only monomer-consuming reactions taking place, together with their rate constants, ...
Author: Krzysztof MatyjaszewskiFor instance, if the relative importance of enthalpic and entropic effects is understood, reactivity ratios can be manipulated by varying the polymerization temperature. If polar effects are known to be important, reactivity ratios can ...
Author: Kunio Esumithe number of binary particle is the reactivity of the particle collision, k collisions pp per unit time, and N 1 is the singlet particle number density. Solving Eq. (9) gives pp , The particles characteristic reduces to collision half ...
