The present invention relates to a branched modifier and a composition comprising more than 25 wt % (based on the weight of the composition) of one or more linear ethylene polymers having a g'of 0.97 or more and an Mof 20,000 g/mol or more and at least 0.1 wt % of a branched modifier where the modifier has a g&#x2032;of less than 0.97, wherein the ethylene polymer has a g&#x2032;of at least 0.01 units higher than the g&#x2032;of the branched modifier.

Modified polyethylene compositions

A process comprising contacting a catalyst system with one or more olefins in a bubble column reactor. Also, a polyolefin copolymer composition comprising ethylene, propylene and optionally a Cto Calpha olefin; said composition having a bimodal distribution with respect to composition distribution, molecular weight distribution or a combination thereof; an Mw of 10,000 g/mol or more; and/or at least two melting peaks in a DSC heating cycle with a difference in melting temperatures of at least 5&#xb0; C.

Polymerization process for production of polymer

An in-reactor polymer blend including (a) a propylene-containing first polymer; and (b) propylene-containing second polymer having a different crystallinity from the first polymer. The polymer blend has a melting temperature, Tm, of at least 135&#xb0; C., a melt flow rate of at least 70 dg/min, a tensile strength of at least 8 MPa, an elongation at break of at least 300%.
