Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixed solvent of ethylene carbonate and methyl ethyl carbonate was prepared at a capacity ratio of 10:30. To the mixed solvent, 2% by weight of vinylene carbonate, 2% by weight of vinylethylene carbonate, 5% by weight of fluorobenzene, and 5% by weight of phosphazene were added, obtaining a mixed solution. LiPF6 was dissolved in this mixed solution at a concentration of 1.5 mol/L, obtaining a non-aqueous electrolyte. obtaining a mixed solution obtaining a non-aqueous electrolyte

Procedure: A 300 mL flame dried round bottom Schlenk flask was charged with α-diimine Pd(II) catalyst X (100 mg) in an argon filled glove box. Upon removal from the glove box, the flask was evacuated and backfilled with ethylene. The catalyst was dissolved in CH2Cl2 (50 mL) and immediately treated with vinylethylene carbonate (12 mL). The resulting orange solution was stirred at 23° C. under an ethylene atmosphere (1 atm) overnight. A small amount of polymer had precipitated out of solution. The polymerization was quenched with MeOH and filtered on a glass frit. The polymer was collected and dried in vacuo at 60° C. for 3 days to afford a tacky solid (800 mg). 1H NMR was consistent with a copolymer containing approximately 99.5 mole % ethylene and 0.5 mole % vinylethylene carbonate monomer units.

Procedure: 3.07 grams (26.9 mmol, MW: 114.10) 4-vinyl-1,3-dioxaolane-2-one, 5.0 grams (24.5 mmol, MW: 204.13) 2-ethylhexyl thioglycolate and 0.402 grams (2.45 mmol, MW: 164.21) 2,2′-azobis(2-methylpropionitrile) (AIBN) were charged in 25 milliliter thick sealed glass reactor. After addition, the reaction mixture was stirred for 22 hours at 110° C. The reaction was then stopped and cooled down to room temperature. The excess of unreacted 4-vinyl-1,3-dioxaolane-2-one was removed by air bath oven at 180° C. under vacuum for 1 hour. The final product was determined by IR, 13C NMR. Yield: 6.0 grams (77%).
