Step polymerizations proceed with second-order kinetics 1/[M] = 1/[M]0 + kt (5) or
DP = 1 + [M]Qkt (6) where [M]Q and [M] are the concentrations of X(or Y) groups
at times 0 and t, respectively. A characteristic of the second-order kinetics is that ...

Since esters are rather inert, other groups such as epoxy, halogen and carboxyl
must be incorporated into the polymer to introduce sites for curing. We have
studied the effect of various ammonium and phosphonium salt catalysts on the
rate of ...

Even in bulk, the reactive groups in a polymerising mixture are diluted by the inert
portions of the chains between the groups. Only in the limit of zero molar masses
of reactants is there zero dilution of reactive groups. Of course, in that limit v is ...
