Structure and Dynamics of Polymers at Surfaces, Interfaces and in a Confined Space. Computer Simulation. — •T. Pakula — Max-Planck-Institut für Polymerforschung, Mainz

Cooperative Motion Algorithm is used to simulate static and dynamic properties of polymer chains in the following specific situations: (1) end functionalized linear chains interacting with surfaces, (2) copolymers of various structure as interfacial agents at A-B interfaces, (3) linear chains under spatial confinement of various dimensionality and (4) block copolymers interacting with surfaces and under shear flow. Static properties of systems are characterized by concentration profiles, changes of chain dimensions and orientation correlations. Dynamic properties are described by relaxation times and diffusion constants of polymers. Simulation results provide information about structure and dynamics of polymer chains with a number of details which are not accessible for experimental and theoretical investigation.
