Abstract
X-ray and neutron reflectivity are used to study the morphology of a triblock copolymer of d-poly(styrene) and poly(2-vinylpyridine) in the form P2VP30-dPS60-P2VP30 deposited as a film on a silicon wafer. Microphase separation leads to a lamellar film which is strongly quantized in layers of about 300 angstrom each and with P2VP at the silicon substrate. The confinement of the polymer ends to the same plane leads for the top layer to a > of the polymer, so that the middle PS part can still wet the air interface completely.
