Technology compatibility

Based on the extensive work, Ghosh and De have concluded that fluoroelastomer and silicone mbber form technologically compatible blends of micro-heterogeneous stmcture with thermal stability between those for the blend components. The blend could be used as a replacement for fluorosilicone mbber.

With respect to higher-throughput analytical methodologies, we have taken two approaches. The first involves the addition of CYP-selective substrates to cell culture and measuring the formation of the relevant metabolites in the media (CYP activity assays). The second approach is to measure CYP mRNA levels using newly developed technologies compatible with 96-well culture formats.

Also, the fundamental problem related to the synthesis of selective and technologically compatible membranes should be deeply considered. The contemporary solution of all these problems will probably determine success at the industrial level. Also of extreme importance is the study of linearization procedures and the development of algorithms for the deconvolution of multiple information at the outputs of multifunctional ACSs, whose future looks bright indeed. 

These two objectives are discussed together because many of the selection criteria for screening compounds are important to fulfill both objectives, namely physical chemical properties and chemical purity and stability. Especially with respect to optimizability, a violation of the selection criteria discussed here is not a definite reason for exclusion, but it is a liability of the compound, which needs to be addressed during the optimization of the compound that follows the discovery of the hit. The more such liabilities a compound exhibits, the more difficult the optimization of a lead compound will be. Also, not every violation of a technology compatibility criterion is a hard reason for exclusion, but rather it increases the potential of a compound to cause artifacts under a certain assay technology appropriate experimental procedures are required to detect these artifacts. 

The terms polymer blends and polymer alloys are defined in Chapters 1 and 2 of this Handbook. In the trade literature, they have been used interchangeably. In the context of current discussion, we will treat all of them simply as polymer blends, except specifying, where possible, the origin of the technological compatibility between the components in each type of blend. Table 15.1 fists the commercially available polymer blends according to their primary structural categories (Figure 15.1). 

To be useful, most commercial polymer blends are either designed or selected to have some degree of the technological compatibility between the components to resist delamination and loss in ductility. Compatibility is defined here as the ability for the polymer components to co-exist either as molecularly miscible or as morphologically distinct phases, but interfacially stabilized, without a tendency for delamination. 

The technological compatibility in polymer blends can result from any of the following mechanisms ...

Some factors that may arise include whether the match is being made to solvent or water based material. In certain instances the component cannot be painted in a water based system as is the body of the automobile. This can be a tough issue if the standard is also not created in the same system and has never been tested for that type of technology compatibility. 

The lower left qnadrant represents the simple blends. One type of TPE blend is the TPO, which is a simple polymer blend of a rigid thermoplastic polymer with a technologically compatible (not necessarily thermodynamically compatible) elastomeric polymer. Each of the polymeric components exists in its own phase (with its own Tg or The properties of the blend are partly predictable by the properties of the com nents however, the phase morphology is also extremely important. The hard phase must be continuous for the blend to be thermoplastic. Commercial TPO blends include those of EPDM rubber with PP or polyethylene (PE). Another type of simple polymer blend is that of poly(vinyl chloride) and nitrile rubber (NBR). This may have been the first useful rubber-plastic blend.
