Abstract
Small-angle neutron scattering experiments by interpenetrating network s of poly(carbonate-urethane) and polyvinyl pyridine reveal that there is some degree of microphase separation at all compositions, possibly , in some compositions, into a bicontinuous phase. The domain size is some undred angstroms in the samples with only one glass transition te mperature, and is much smaller than the domain size for samples with t wo glass temperatures.
