摘要:
Disclosed is a novel polymeric compound poly(benzoic acid) which is a linear polymer consisting of the 1,4-phenylene linkages, each phenylene group having a carboxyl group. Poly(benzoic acid) can be prepared by hydrolyzing a poly(alkyl benzoate) in the presence of an acid or alkali. The thus obtained poly(benzoic acid) can be converted into a poly(p-phenylene) by the decarbonation reaction thereof in an organic solvent such as quinoline in the presence of metallic copper dust or a copper (II) compound such as copper (II) oxide and copper (II) carbonate hydroxide.
摘要:
A 3-n-alkylthiophene polymer of the general formula: ##STR1## (wherein n stands for an integer in the range of 5 to 11 and m for an integer in the range of 80 to 350) and a composition containing this polymer.
摘要:
A polymer composition having poly-[2,5-(3-ethylthienylene)] doped with an anion is obtained by electrochemically polymerizing 3-ethylthiophene in an anion-containing salt as an electrolyte. Poly-[2,5-(3-ethylthienylene)] is obtained by electrochemically reducing the polymer composition thereby removing the anion therefrom. The aforementioned polymer composition and poly-[2,5-(3-ethylthienylene)] are novel substances.
