Stimulated by the concern for environmental problems that arose during the 1970s and 1980s, related both to global and national questions of sustain ability, the German government committed itself to advancing ecosystem research as a central component of planning for environment- ally, economically, and socially sound policies and for resource manage- ment during the 21 st century. Ecosystem research has been promoted at institutions spread throughout the country and that are favorably struc- tured to conduct interdisciplinary studies.

The study of the relationship between the structure, morphology and properties of polymer films has significantly progressed in recent years through the use of a number of phyiscal techniques - some new and some old. These methods include small and large angle x-ray diffraction, bire fringence, light scattering, infrared dichroism, fluorescence polarization, light and electron microscopy and interferrometry. This collection of papers, most of which were presented at a symposium at the Boston American Chemical Society Meeting in April, 1972, represent a collection of recent studies using many...
