abstract |
The invention refers to a linear, isotactic polymer which has a structure of one or several C 2 to C 20 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 [mmmm] pentad concentration, the polymer having a mean molecular weight Mw within the range of from 100,000 to 800,000 g/mol and a Tg of from −50 to 30° C. |
