A review covering the LDPE and EVA processes (Table 1) run In autoclave (150-200 MPa, 2-3 reaction zones with individual initiators) and tubular reactors (200-350 MPa) at 150-300degreesC (Fig. 1). Recent R&D trends are focused on new Initiators to keep process economy and polymer structure under better control, on new copolymers to be processed In the existing equipment, and on the maximum use of the existing production capacity. Homopolymers are menaced by metallocene-based new-generation polyolefins, e.g., new-generation PE is expected to replace HDPE and EVA In films and extruded coatings. Reactor preferences (autoclave vs. tubular) are difficult to foresee.
