Elimination of ethylene carbonate from poly[ethylene co 2,2‐bis(4‐phenylene)‐propane carbonate]

Elimination of Ethylene Carbonate fromPoly[ethylene co 2,2-bis(4-pheny1ene)propane Carbonate]Pyrolysis of polycarbonates can, in some instances, yield polyethers.Thus J. W. Hill pyrolyzed poly( decamethylene carbonate) and obtained poly(decamethy1ene oxide) as one product:' /-R-0-(3-0) + (-R-O-)vL
