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