摘要:
The present invention relates to butene-1 copolymers containing up to 40% by mol of ethylene and/or propylene derived characterized by the following properties: d) Product of the reactivity ratios r1·r2≦2; e) Content of butene-1 units in form of isotactic pentads (mmmm)>98%; and f) absence of 4,1 insertions of butene units.
