Arm retraction dynamics in dense polymer brushes
Michael Lang, Marco Werner, Ron Dockhorn +1
Large scale Monte Carlo simulations of dense layers of grafted polymer chains in good solvent conditions are used to explore the relaxation of a polymer brush. Monomer displacement…
Effect of Topology on the Conformations of Ring Polymers
Michael Lang, Jakob Fischer, Jens-Uwe Sommer
The bond fluctuation method is used to simulate both non-concatenated entangled and interpenetrating melts of ring polymers. We find that the swelling of interpenetrating rings upo…
Elasticity of Phantom Model Networks with Cyclic Defects
Michael Lang
The impact of finite cycles on the phantom modulus in an otherwise perfect network is computed exactly. It is shown that pending cycles reduce the phantom modulus of the network by…
Short Cyclic Structures in Polymer Model Networks: A Test of Mean Field Approximation by Monte Carlo Simulations
Michael Lang, Konrad Schwenke, Jens-Uwe Sommer
A mean field rate theory description of the homo- and co-polymerization of -functional molecules is developed, which contains the formation of short cyclic structures inside the…
On the Structure of Star-Polymer Networks
Konrad Schwenke, Michael Lang, Jens-Uwe Sommer
Using the bond fluctuation model we study polymer networks obtained by endlinking of symmetric 4-arm star polymers. We consider two types of systems. Solutions of one type (A) of s…
Monomer Fluctuations and the Distribution of Residual Bond Orientations in Polymer Networks
Michael Lang
In the present work, four series of simulations are analyzed: entangled model networks of a) mono-disperse or b) poly-disperse weight distribution between the crosslinks, c) non-en…
