Combination polymerization

In introductory biochemistry, one becomes familiar with amino acids (aa) and how they combine (polymerize) to become peptides and proteins. Proteins fold into three-dimensional shapes and become enzymes, the catalysts of...

Part of the above discrepancies may arise from problems with sample purity. Aminophe-nols autooxidize even more readily than most other classes of phenols. They readily form quinones and quinonimines and then these combine, polymerize, dehydrate and otherwise contaminate samples and confound chemists. Or, at least, that is how we understand the over 40 kJ mol difference between the enthalpies of formation of solid phase 3,3 -diamino-4,4 -dihydroxydiphenylmethane and its isomer in which the locations for the amino and hydroxy groups are exchanged . ...

While it is possible that future polymeric batteries will be all-polymeric solid-state batteries, it is predicted, however, that the most promising solid state batteries will combine polymeric electrolytes with nonpolymeric electrode materials such as TiS2, VeOis, Li or LiAl, the specific capacity of which surpasses that of polyacetylene electrodes. 

In these blends, dispersion of the two phases is most often achieved by intensive mechanical mixing, but in the polypropylene-EPR combinations, polymerizing the finely dispensed elastomer phase simultaneously with the hard polypropylene is possible [13-15]. 

As well as functional monomer polymerization and PPM, one-pot polymerization has also been used to obtain a highly functionalized polymer. One-pot polymerization combines polymerization with other compatible reactions to achieve the target new polymer in the same reactor. In contrast to functional monomer polymerization, one-pot polymerization can form the functional monomer in situ and thus avoid the purification step necessary with functional monomer synthesis. This approach also avoids hindrance from the polymer backbone, leading to a higher modification yield compared with the normal PPM approach. With less time and cost, the desired polymer can be achieved and functionalized with a high yield in one pot. Some reactions such as the CuAAC click reaction and enzymatic transesterification have been used for construction of a one-pot polymerization system with controlled/living radical polymerization approaches to achieve new functional polymers [119-125]. 

There have been a considerable number of poly-rotaxanes reported in which the rotaxane motifs combine polymeric and discrete components. The most common of these involve preformed molecular rotaxanes acting as ligands, with the axle component containing coordinating groups at either end. Reaction of these rotaxane-based ligands with metals then gives polymeric structures. An example of a ID polymer constructed in...
