Europium systems

Figure 43 shows the result of applying a short pulse of light to the terbium system while the light from the europium system is monitored. Stroboscopic... [Pg.278]

Stereospecific polymerization of 1,3-dienes (10-18) (to butadiene) and isoprene homo- and copolymers), dimerization of propene (19) and recently stereospecific polymerization of acetylene (20) to high cis-content polyacetylene have all been reported using lanthanide catalysts. Sen (21) has reported the preparation of cationic europium systems (which perhaps function as cationic initiators) for polymerization of norbornadiene and 1,3-cyclohexa-diene. [Pg.460]

Diffusion of energy in the europium system has been discovered to be the... [Pg.56]
