Full text not available from this repository. This phenomenon is known as surface migration. We present a theoretical framework to explain this phenomenon and to quantitatively predict the amount of material that migrates to the interface. temperature, mens replica hermes briefcase
surface tension and the mixing parameter (that determines whether the bulk polymeric phase is mixed or phase separated). The main hypothesis presented in this thesis is that the elasticity of the polymer matrix through which the low molecular weight species migrates to the free interface is an important parameter that has not been taken into account so far. This raises the interesting possibility of controlling surface migration by tuning matrix rigidity by changing polymer elasticity with broad industrial applications.
