Abstract After a short survey of the first indications on the existence of stereoregularity in the main chains of the vinyl polymers, the first syntheses of stereoregular poly(vinylethers) and… (More)
The molar rotatory power in hydrocarbon solution of poly[(S)-1-methyl propyl]vinyl ether (I) is far higher than that of poly[(S)-2-methyl butyl]vinyl ether (II). With increasing temperature, the… (More)
Propylene was polymerized in the presence of hydrogen using (−)(R) (EBTHI)Zr(CH3)2 (Ia) or (+)(S)(EBTHI)ZrCl2 (Ib) as catalyst precursor and (-Al(CH3)-O-)n as co-catalyst. The polymers were… (More)
Previously estimated optical yields in the asymmetric hydroformylation of styrene (up to 95%) have been found to be considerably lower (up to 73%).
Abstract The amino—carbonylation of aliphatic aldehydes proceeds with exceptionally high selectivity. Some aspects of the reaction mechanism are discussed which may explain the failure to obtain an… (More)
Publisher Summary This chapter discusses stereoscopic polymerization of α-olefins. The simplest scheme of formation of isotactic polymers is represented by the polymerization processes of the ionic… (More)
