Homogeneous polymer blends

Figure 5.19 Homogenous polymer blend of 2,7-diamido-l,8-naphthyridine (DAN) functionalized polystyrene and urea of guanosine (UG) functionalized poly(butyl methacrylate) (14), based on the four-point complementary complex formation between DAN and UG.

Application of the dual mode sorption and diffusion models to homogeneous polymer blend-gas systems 26,65) and filled polymers 66) has also been reported. 

Though miscibility is by no means a prerequisite to commercial utility, homogeneous polymer blends are more convenient from the standpoint of being able to predict properties or processing characteristics.

Eventually, an implantable, biodegradable medical device can be formed from a homogeneous polymer blend. The fabrication proceeds in detail as follows (12) ... 

In glassy homogeneous polymer blends below Tg, their internal morphology plays only a secondary role, in contrast to the temperature, which is the major parameter governing the yielding, especially in compression, shear, and hardness measurements. 

Due to experimental difficulties the effect of pressure on the phase behaviour of polymer mixtures has been studied only quite recently. First information was collected some twenty years ago from calculations with free volume models, based on p-V-T data on molten homopolymers [42] and later on on homogeneous polymer blends [43].

Miscible or homogeneous polymer blends These mixtures are often made from polymers with similar chemical structures, resulting in a polymer blend with a single-phase structure. One glass transition temperature is observed. 

In the rare situation of a homogeneous polymer blend, interactions involving dissimilar macro-radical/macromolecule pairs are theoretically possible. Interactions in the homogeneous two-component system PMMA/bisphenol A polycarbonate have been explained on the basis of PMMA radical attack on the polycarbonate chain.
