Polymer applications technology

Any list of copolymer applications would be as extensive as the applications of polymers in general. We shall only consider a few items in which the two-component nature of the copolymer plays an explicit role in determining the properties of the polymer. In addition, we shall examine several additional concerns which come up when applications technology is considered. 

The predominant applications of present day metal/polymer adhesion technology are for the development of strong metal-to-metal structural adhesive joints and durable protective coatings. 

Different types of PVC exist on the market. The two principle types are suspension and paste-forming PVC the latter includes the majority of emulsion PVC polymers. The plasticizer applications technologies associated with these two forms are distincdy different and are discussed separately. Details of the polymerization techniques giving rise to these two distinct polymer types can be found in many review articles (5,28) (see Vinyl POLYMERS, (VINYL CM.ORIDE POLYPffiRS)). 

Many of the applications of conductive polymers utilize their unique properties and advantages over other material systems, for example low density and controllable electrical properties. The following examples demonstrate the versatility of conducting polymers in technology. 

To achieve the main process requirements (ability to be applied by different methods by hand, spray, electropaint), and to provide the necessary decorative, physical, and mechanical properties, organic solvents are used in concentrations up to of about 50% to modify the viscosity and other rheological characteristics of the some polymer compositions. During the application and formation of the coating, the solvents evaporate into the atmosphere as pollutants. This serious disadvantage of formulations based on the use of solvents as "intermediate" carriers has provided the incentive to develop polymer compositions and application technologies which yield the required rheological characteristics either without solvents, or at least with low concentrations of them.

These interpolymers based on ethylene and styrene are an integral part of an exciting new generic class of materials, offering unique opportunities for innovative developments in basic polymer chemistry, catalyst and process development, materials science and engineering and application technology. 

The journal deals with not only every type of cellular polymer, from elastomeric materials to rigid plastics, but also raw materials, manufacturing processes, and application technology. Coverage includes Conference Reports, Conferences and Seminars Listings, Selected Abstracts, and Book Reviews. Averages three to five articles per issue.

The development of solid polymer electrolyte cells is being actively conducted at General Electric Co. (13) and at Brown Boveri Research Center, Baden, Switzerland (14). As the name implies, the solid polymer electrolyte technology uses a solid polymer sheet as the sole electrolyte in the cells. It also acts as the cell separator. The majority of the present applications use Nafion with a thickness of 10-12 mils (13). Selected physical and chemical properties of Nafion 120 membranes are given in Table I. The membrane is equilibrated in water to approximately 30% water content prior to fabrication into a cell assembly. The hydrated membrane is highly conductive to hydrogen ions. It has excellent mechanical strength, and it is very stable in many corrosive cell environments.
