Rubber elasticity shell

Most interesting is the large increase in reinforcement even for small bound rubber thicknesses. Let us briefly discuss the advantages of the model. They find that the results obtained are realistic for small as well as intermediate filler concentrations, i.e. they are in accordance with experiments at least qualitatively. For the core-shell systems they have provided exact calculations of intrinsic moduli for various special forms of core-shell elasticity, i.e. soft spheres, hard spheres with soft surfaces, etc. These results contain no fit parameters and in principle both compressible and incompressible media are accessible.

One question of interest at this stage is how would the linear viscoelastic properties be affected if the PS dispersed phase is replaced by an elastic component. The same PMMA used before has been blended with rubber particles over a wide range of PMMA/Rubber composition (95/05, 90/10, 85/15, 80/20, 70/30, and 50/50. As mentioned before the rubber particles consist of a core-shell poly(butylacrylate-co-styrene)-PMMA type. 

This property may indicate the rubber like nature of the matrix the indenter stress is probably distributed to other parts of the shell and stored as elastic energy which is released when the indenter is raised. ...
