Multi-phase polymers

It has already been shown above that the dCp/dT signal readily provides fruitful information about multi-phase polymer materials. Measurement of the ACp values of the pure shell and core phases at their TgS leads to... 

Thermoplastic elastomer (TPE) blends have been broadly studied as a new class of materials. TPEs offer various advantages and require no state-of-the-art processing machinery, while scrap and rejects are recyclable. Blends can be homogeneous, phase separated or both. TPEs are multi-phase polymer systems consisting of hard and soft domains that can be copolymers or mechanical blends. This phase separation leads to materials having unique and viable commercial physical properties. TPEs exhibit the thermoplastic characteristics of the hard thermoplastic phase, and resilience as a result of the rubbery domains. TPEs based on natural rubber (NR) and thermoplastic blends are known as thermoplastic natural rubber (TPNR) blends. There are two types of TPNR, namely thermoplastic polyolefin (TPO) and thermoplastic vulcanizate (TPV).3... 

The use of polymers seems limitless in its variety the technology associated with these uses rich in its sophistication. One of the main reasons for this is that polymers are virtually never used alone, but always in combination with other materials. These added materials may be stabilizers, plasticizers, reinforcing fibers, pigments or other polymers, formulated into multi-component systems with properties well suited for specified applications. Obviously, in multi-phase polymer systems, interfaces and interphases must exist. It seems obvious intuitively that the nature of these interfaces and interphases will affect the performance of the system as a whole. Inherent in that statement is the link between component interactions on the one hand, and the rheological, physico-chemical and mechanical properties of the system, on the other.

These types of microheterogeneity are inherent in all polymer systems, filled with particulate and fibrous fillers, in two-phase and multi-phase polymer systems (mixtures of polymers with discrete and continuous distribution of components), as well as in polymer glues, coatings, fiber-reinforced plastics, i.e., in all polymer composites. However, in polymers with mineral reinforcement, microheterogeneity appears as a result of interfacial phenomena only in the... 

It is useful to consider the deformation of single- and multi-phase polymers separately. Unfilled elastomers, polymer glasses and polymer single crystals... 

The aim of the study is to improve the understanding of structure-property-relationships of multi-phase polymer materials. In doing so the nanostructural parameters are correlated with the mechanical behavior of the materials.
