Abstract

This paper describes a novel method of preparing two alternating vinyl alcohol copolymers, poly(vinyl alcohol-co-ethylene) and poly(vinyl alcohol-co-ethylene-co-1,4-butadiene). The chemistry involves the ring-opening metathesis polymerization of organoborane monomers, such as 5-cyclooctenyldiethylborane. The borane polymer thus obtained gave upon oxidation a novel polymer structure of poly(vinyl alcohol-co-ethylene-co-1,4-butadiene) with an alternating molecular structure. The borane polymer could also be further hydroborated prior to the oxidation reaction. This fully hydroborated polymer resulted in an alternating copolymer of poly(vinyl alcohol-co-ethylene), which was found to be very thermally stable and began to lose weight only at temperatures above 400°C.
