The effect of the rigidityand shape of a bulky kinetic chain element on the basic characteristics of local mobility are investigated by using a dynamic polymer chain model. The results are used to evaluate the characteristic times of local motions for a poly(amid0imide) molecule in solution. The effective length of a kinetic segment is determined f o r flexible chain polymers poly(methy1 methacrylate) and poly(parach1orostyrene) on the basis of experimental data o n local mobility. Eigenschaften des kinetischen Elementes und lokale Beweglichkeit in Polymerketten Der EinfluS von Steifheit und Gestalt eines kinetischen Kettenelementes auf die wichtigsten Charakteristika der lokalen Beweglichkeit werden fur ein dynamisches Model1 der Polymerkette untersucht. Die Ergebnisse werden verwendet, um die charakteristischen Zeiten der lokalen Bewegungen cines Poly(amidoimid)-Molekuls in Losung zu berechnen. Auf der Basis experimenteller Werte der lokalen Beweglichkeit wird die effektive Lange des kinetischen Segments fur flexible Polymerketten von Poly(methy1methacrylat) und Poly(parach1orstyren) bestimmt.

## Abstract Using a lattice description, the short‐ and medium‐scale dynamics of the heterogeneous model of main‐chain liquid‐crystalline polymers have been considered. Chain mobility is assumed to occur by means of three‐ and four‐bond kinetic‐unit jumps. Mobility and force coefficient tensors, an
Using specular neutron reflectivity, we have measured the structure of tethered polymer layers immersed in a solution of mobile chains of the same chemical composition. The tethered polymer layer is a stable Langmuir film of a diblock copolymer spread on the air-liquid interface of a selective solve
