Notes:
Thiocarbonyl fluoride, fluoroalkylthio acid fluorides, and fluorothioketones are converted to high molecular weight polymers by anionic initiation at low temperatures. Amorphous poly(thiocarbonyl fluoride), (CF2S)n, is a tough elastomer that is highly resilient. Poly(thiocarbonyl fluoride) has a melting point of 35°C. and slowly crystallizes at room temperature to an opaque, stiff plastic. The glass transition point of the polymer is very low, being -118°C. as determined by the torsion pendulum method. Poly(trifluorothioacetyl fluoride) and polyhexafluorothioacetone are also elastomeric, but neither has the high resilience that is characteristic of poly(thiocarbonyl fluoride). Polyhexafluorothioacetone slowly depolymerizes at room temperature.
