Research Abstract

A poly[(acylocy)aloxane] was synthesized by a multistage reaction of triethyl-aluminum with water, 3-ethoxy propanoic acid, and m-anisic acid and then dry-spun into fine filaments. The asspun filament thus obtained was calcined in an electric furnace in nitrogen atmosphere up to 1200 ゜c.
The electric volume conductivity of the resultant alumina filaments was ecaluated at temperatures ranging from 0 to 400 ゜c by using a four terminal technique. The volume conductivity was an increasing function of the calcination temperature and of the measuring temperature as well. The highest value ca. 1x10^2 S cm^<-1>, wsa recorded for the filament heated up to 1200 ゜C.
An alternative principle employed in the present study was the use of bi-component polyblends comprising poly[(acyloxy)aloxane] and one of the thermally stable linear polymers with superior spinnability. An ultra high molecular weight polye-thylene and a moderate molecular weight poly(acrylo nitrile) were employed as the co-component of the blends.
A concentrated decaline solution of poly[(acylocy)aloxane]-polyethylene blend was easily spun inyo fine filaments and drawn 10 times or higher in an oven at 150 ゜C, eliminating decaline from the filament. Unfortunately poor conductivities were obtained for the alumina filament prepared from the blend of this combination.
The use of poly(acrylo nitrile), a precursor polymer for the commercial carbon fibers, as the co-component was much effective and gave an excellent coductivities, 2x10^1 to 4x10^1 S cm^<-1>.
