Katalysatorkombination og fremgangsmåde til fremstilling af lineære, isotaktiske polymerer

The invention refers to a linear, isotactic polymer which has a structure of one or several C2 to C20 olefins, of which the isotacticity, due to a statistic distribution of stereoscopic errors in the polymer chain, is within the range of from 25 to 60 % of ÄmmmmÜ pentad concentration with the provis...

Zusammenfassung:The invention refers to a linear, isotactic polymer which has a structure of one or several C2 to C20 olefins, of which the isotacticity, due to a statistic distribution of stereoscopic errors in the polymer chain, is within the range of from 25 to 60 % of ÄmmmmÜ pentad concentration with the proviso that an arbitrary or rather regular sequence of isotactic and atactic blocks is excluded, the polymer having a mean molecular weight Mw within the range of from 100.000 to 800.000 gms/mol and a TG of from -50 to +30 DEG C.
