The aim of this work is to theoretically investigate the effect of impurities on the MWDs of the polymers produced when anionic polymerizations are carried out in SS and periodic CSTRs. The effect of impurities contained in the monomer feed is theoretically investigated, in relation to ´living´ anionic homopolymerizations carried out in isothermal and homogeneous CSTRs. In the SS operation, the total produced polymer always exhibits a Schulz-Flory distribution, with a NACL which dec...
The aim of this work is to theoretically investigate the effect of impurities on the MWDs of the polymers produced when anionic polymerizations are carried out in SS and periodic CSTRs. The effect of impurities contained in the monomer feed is theoretically investigated, in relation to ´living´ anionic homopolymerizations carried out in isothermal and homogeneous CSTRs. In the SS operation, the total produced polymer always exhibits a Schulz-Flory distribution, with a NACL which decreases as the impurities are increased. The result is reasonable bearing in mind that the system is dynamically equivalent to a continuous free-radical polmerization with initiation, propagation and termination by disproportionation.
