| Abstract
| - The synthesis of a new methylene−(vinyl alcohol) copolymer, poly((vinyl alcohol)2-alt-methylene) (MVOH), by ring-opening metathesis polymerization with ruthenium catalysts is reported.Unsaturated cyclic 1,3-diols were protected with a di-tert-butylsilyl group to form strained cyclic olefins.The molecular weights of the polymers were controlled by varying the monomer-to-catalyst ratios or bythe addition of a chain transfer agent. Hydrogenation and subsequent deprotection of the ROMP polymersyield the MVOH copolymer structure which was confirmed by 1H NMR and 13C NMR spectroscopies.Thermal properties of the corresponding MVOH copolymer are reported.
