Abstract (en)

[origin: WO2012134713A2] This invention relates to a composition comprising a multiblock polyolefin represented by the formula: PO-(-C=C-Z-)n-C=C-PO* (I) or PO-(-C-C-Z-)n-C-C-PO* (la) wherein Z is the portion of a cyclic monomer having at least one internal double bond that remains after a ring-opening metathesis reaction; PO and PO* are each independently polyolefins; and n is 1 to 10,000; and a process to produce such comprising contacting an alkene metathesis catalyst with a dimer of vinyl terminated polyolefins, and a cyclic hydrocarbyl monomer comprising at least one internal double bond.
