FLUOROCARBON POLYMERS. PERFLUOROPOLYTOLYLENES

Perfluoro-polytolylenes were prepared by treating 2-chloroheptafluorotoluene with magnesium in tetrahydrofuran. Polymerization occurred readily at 0C. High molecular weight polymers were prepared by refluxing the mixture as long as 5 days. Soluble polymers were obtained having molecular weights of 5...

Description
Summary:Perfluoro-polytolylenes were prepared by treating 2-chloroheptafluorotoluene with magnesium in tetrahydrofuran. Polymerization occurred readily at 0C. High molecular weight polymers were prepared by refluxing the mixture as long as 5 days. Soluble polymers were obtained having molecular weights of 5100; 35,600; 88,500; and 200,000. These polymers exhibited good thermal stability in a vacuum of 600C. (Author)
