Reaction Steps

A carbon monoxide/ethylene/1-dodecene terpolymer was prepared by charging 180 ml of methanol and 78 ml of 1-dodecene to a magnetically stirred autoclave of 300 ml capacity. After the contents of the autoclave had been heated to 65° C., a 1:1 carbon monoxide and ethylene mixture was introduced under pressure until a pressure of 55 bar was reached. A catalyst solution was then introduced comprising 18 ml of methanol, 0.03 mmol of palladium acetate, 0.06 mmol of copper para-tosylate, 0.036 mmol of 1,3-bis(diphenylphosphino)propane, and 0.3 mmol of 1,4-benzoquinone. The pressure in the autoclave was maintained by introducing additional amounts of the 1:1 carbon monoxide and ethylene mixture. After 3 hours the polymerization was terminated by cooling to room temperature and releasing pressure. The polymer was filtered, washed with methanol and dried at 70° C.
