Summary
In polymer melts of protonated and deuterated polystyrene (PS and d-PS) surface segregation of the d-PS occurs at temperatures and compositions in the one phase region close to the coexistence curve for phase separation. A neutron reflection test on a polymer blend containing 10% volume fraction of d-PS has shown that a thermal treatment caused a surface enrichment of d-PS up to 28%. The experiment demonstrates that neutron reflection measurements can generate detailed information on surface enrichment phenomena in polymer blends.
