Preparation method of antistatic soluble polypyrrole

Some chemicals with cas registry numbers like 10045-89-3 and 77214-82-5 are also used. Preparation method of antistatic soluble polypyrrole. Jang, Gwan Sik; Oh, Eung Joo (S. Korea ). Repub. Korean Kongkae Taeho Kongbo KR 2001096050 A 7 Nov 2001,No pp. given (Korean). (Korea, Republic Of). CODEN: KRXXA7. CLASS: ICM: C09K003-16. APPLICATION: KR 2000-19958 17 Apr 2000. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 76 A method for prepg. an antistatic polypyrrole, an antistatic film and an antistatic material are provided, which polypyrrole is stable in air, has good elec. cond., is sol. in an environment-friendly protic solvent and can be coated uniformly, thereby being used as an antistatic film for packaging the electronic component or an antistatic flooring material. The prepn. method of antistatic polypyrrole comprises reacting the pyrrole monomer with a dopant under slow stirring in the presence of an oxidizing agent at 0° for 1-70 h, and drying the product under vacuum. Preferably the oxidizing agent is selected from ferrous ammonium sulfate, iron sulfate, potassium permanganate, potassium persulfate, and ferric toluene sulfonate. .
