Preparation of ethene/carbon monoxide copolymers using copper-based catalysts and their characterization by pyrolysis-gas chromatography

Ethene/carbon monoxide copolymers were prepared using the catalyst system Cu(OAc)2/dppp (1,3-bis(diphenylphosphino)propane)/p-toluenesulfonic acid (p-TsOH) or BF3·OEt2/p-benzoquinone. Pyrolysis-gas chromatography proves the alternating structure of the copolymers.
