| Abstract: | Structural and phase transformations in the course of the multistage physical aging of semi-inter-penetrating polymer networks
based on crosslinked polyurethane and linear polystyrene are studied. Dynamic mechanical and thermophysical studies make it
possible to assume that, as a result of the physical aging, a heterogeneous polymer system experiences structural rearrangements
and the fraction of the inter-facial region increases. |
