TL;DR: In this paper, the key to successful metathesis polycondensation chemistry was described, which can occur exclusively if carbocation formation can be obviated through the proper choice of a Lewis acid free catalyst.
Abstract: This paper describes the key to successful metathesis polycondensation chemistry. Model compound reactions with styrene and styrene derivatives show that metathesis chemistry can occur exclusively if carbocation formation can be obviated through the proper choice of a Lewis acid free catalyst. Vinyl terminated oligo(octenylene)s were synthesized in this manner, which in turn were converted to polymers of high molecular weight.
