The invention relates to a method for producing linear butenes from methanol. The problem addressed is that of specifying such a method in which the methanol used is converted, to the largest possible extent, into butenes. The problem is solved by combining a methanol-to-propylene process with a metathesis reaction by means of which the propene obtained from the methanol is converted into linear butenes.

Process for preparing linear butenes from methanol

A film containing an interpolymer of ethylene and a 3-substituted Calkene is prepared using a catalyst system comprising a Ziegler Natta or chromium oxide catalyst.

An alkene interpolymer is prepared by polymerizing at least one 3-substituted Calkene and at least one Calkene in a gas phase polymerization using a polymerization catalyst system.
