The particular case of polymer-oligomeric compositions creates new technological possibilities such as the preparation of foamed articles directly at the place of utilization by foaming solutions or pastes at room temperature or sl tly elevated temperatures. It als) leads to a considerable reduction of enei consumption as cOTii ed to traditional processing methods (extrusion, casting and pressing). 

On one hand, inhibited films employ traditional process methods and equipment used for molding film materials. On the other hand, special operations and auxiliaries are needed to modify the polymer base with Cl (Fig. 2.4). A number of methods of combining Cl with the polymer matrix are unique and patented. 

Figure 3.15 Isoprene polymerisation in the presence of VOCl3-Al(f-C4H9)3 (1-4) and VOCl3-Al(/-C4H9)3-piperylene (5-8). Traditional process method (1, 5), catalytic system formation (3, 7) reactive mixture (4, 8) and hydrodynamic impact on catalyst particles (2, 6) in the turbulent mode. V/Al/piperylene = 1/2.4/5, Cy = 6 mmol/1, = 1.5 mol/1, the catalyst is matured for 35 min at 0 °C...

Figure 3.16 Butadiene polymerisation conversion curves in the presence of a TiC -Al(i-C4H9)3 catalyst and traditional process method (1) and preliminary reaction mixture formation in a turbulent mode (2). Al/Ti = 1.8, Cj, = 5 mmol/1 and = 1.5 mmol/1, catalyst is matured for 30 min at 0 °C...

As with a number of the other ceramics discussed, ferrites are most often prepared by traditional processing methods using oxide and carbonate precursors of the various cations. Doping and firing atmosphere control are also frequently used, depending on the particular application, to improve specific material properties, such as resistivity. ... 

In this chapter, a number of non-traditional processing methods that have been developed to modify starch properties for a wide variety of end-use applications have been reviewed. For example, annealing and heat-moisture treatment have been shown to modify the swelling...
