Study of the effects influencing additive migration in polymers

Nanostructure Evolution Mechanisms During Slow Load‐Cycling of Oriented HDPE/PA Microfibrillar Blends as a Function of Composition

“…Consequently, the nanoscopic strain in the disordered fraction would increase from cycle to cycle, whereas the probed ε n would decrease slightly, as is observed in the experiments. In the literature similar softening effects of compatibilizers on the matrix of nanocomposites have been reported [43,44] and sideeffects of additive migration in blends and composites have been studied [45][46][47] . By the way, migration of compatibilizer into the polyamide cannot be studied by means of SAXS data from the studied materials.…”

“…This result indicates the complexity of composite design, because the desired effects of an additive or a processing step may be accompanied by side effects [43][44][45][46][47] .…”

Pharmaceutically Used Plasticizers

“…The interfacial mass transport to the surrounding medium has been found to be the limiting step rather than diffusion of the plasticizer through the matrix to the surface. This rate is usually a function of temperature and initial plasticizer concentration (Foldes, 1998). If plasticizers leach out to a liquid, polymers fail to retain their flexibility while the loss of plasticizers leaves the polymers inappropriate for the desired application.…”

Role of pigments in the stability of polyethylene systems

“…[17] Photostability of HDPE film containing surface treated phthalocyanine pigment If the assumption described above is valid, a coating of the pigment particles with a layer hindering the interaction with the stabiliser molecules should improve the stability. For this purpose a layer of reactive surfactant (RS) [11] was applied.…”
