## Abstract **Summary:** Fully linear polyethyleneβbased latexes have been prepared by the hydrogenation of polybutaβ1,4βdiene dispersions. The latter were synthesized via dispersion ringβopening metathesis polymerization of cyclooctaβ1,5βdiene, and hydrogenated using RuCl~2~(PPh~3~)~3~ as catalyst
ses. Their relative total energies are 0, 0.4, 4.4 and -3.6 kcalmol-I , respectively.1111 Although the difference in energy between the (q2-0,C-HNCO)(q2-C,N-HNCO) and (q2-C,N-HNCO), isomers is small, the calculations are inconsistent with the observed structure. Next, we used molecular mechanics ca
