✦ Synopsis

SYNOPSIS

1 -Chloro-2-@-naphthylacetylene (ClPNA) polymerized in good yields in the presence of MoC1,-based catalysts. The highest weight-average molecular weight of poly(Cl@NA) reached about 3 X lo5. T h e polymer was a yellow solid (absorption cutoff in CHC1,450 nm). It was soluble in toluene, chloroform, etc., and provided a tough film by the solvent casting method. T h e polymer retained its weight up to 300°C in air; it was thermally less stable than poly(1chloro-2-phenylacetylene) but more stable t h a n poly(@-naphthylacetylene). T h e oxygen permeability coefficient (Pop) of this polymer was 19 barrers (25OC), which is fairly small for a substituted polyacetylene. 0 1996 John Wiley & Sons, Inc.
