Polymerization processes future work

Future work can be expected to involve more detailed design of ligands and metal centers with the intention of providing metal complexes that are especially sensitive to changes in viscosity and polarity within different types of monomer/polymer environments. In taking this type of approach, it will be possible to more specifically tailor the emission properties of the probe molecules to applications in a variety of polymerization processes. 

Future work on suspension polymerization will be concerned with new products and with new processes. Much of the new work on recipes and product properties is material-specific and will continue to appear in the patent literature. The development of new processes requires further fundamental investigation. Improvements to existing processes need closer attention to ways in which reactors are operated. These should include the following aspects. 

In the years between 1993 and 1995, Idemitsu and Dow process engineers and chemists worked together to modify and to perfect this new polymerization process, which became the basis for the design of the future manufacturing plants. This was another historically important milestone for SPS commercialization. No other polymer in the world is manufactured in a process quite the same as this, and this development allowed for a cost-effective process to be scaled up to commercial-scale plants. 

U ecent work has led to the synthesis of a variety of compounds in which metal atoms or ions are held in close proximity by chemical linkages. These polymetallic compounds represent a new class of materials that have distinctive chemical and physical properties, and in some systems the properties can be varied systematically by chemical synthesis. The compounds are of interest because of possible cooperative chemical and electronic interactions between the chemically linked metal centers. In the future it may prove possible (a) to create solid state materials that have controllable, and perhaps unusual, electrical conductivity properties (b) to prepare polymeric complexes which in solution have properties that are intermediate between those of solid state materials and those of simple monomeric complexes and (c) to devise chemical systems in which cooperative chemical interactions lead to net, multiple-electron redox processes, or to simultaneous, two- or more site reactions.
