Abstract

The kinetics of end crosslinking in linear polymer melts and the dynamics of the resulting networks is studied using molecular dynamics simulations. Starting from an equilibrated melt, tri- and tetrafunctional crosslinkers are attached randomly to a fraction x of the chain ends. When a free end comes within a short capture distance rx from an unsaturated crosslinker, the chain ends are attached. With a stoichmetric number xs of crosslinkers present, the long time kinetics of the number of free ends and number of unsaturated crosslinkers decay as a power law in time t−a, with a ≈ 0.5. For x ≠ xs, the decay is significantly faster. These “model” networks are then used to show that entanglements play an important role in determining the elastic modulus of the network.
