摘要: Disclosed are processes for preparing monomer complexes that include contacting 2,3,5,6-tetraminopyridine free base in water with 2,5-dihydroxy terephthalic acid dipotassium salt to form an aqueous mixture, and adjusting the pH of the aqueous mixture to within the range of from about (3) to about (5) to precipitate the monomer complex. Processes of polymerizing the monomer complexes, polyareneazoles, filaments and yarns are also disclosed.

摘要: Disclosed are processes for preparing polyareneazole polymers including contacting a molar excess of a free base in water with a terephthalic acid salt to form an aqueous mixture, adjusting the pH to precipitate a monomer complex, contacting the monomer complex with metal powder, and polymerizing the monomer complex. Polyareneazoles, filaments and yarns are also disclosed.
摘要翻译: 公开了制备聚芳腈聚合物的方法,包括使摩尔过量的游离碱与水中的游离碱与对苯二甲酸盐接触以形成水性混合物,调节pH以沉淀单体配合物,使单体配合物与金属粉末接触,并使单体聚合 复杂。 还公开了聚芳ne唑,长丝和纱线。
