The first example of palladium catalysed non-perfectly alternating copolymerisation of ethene and carbon monoxide.

Non-alternating ethene-CO copolymerisation is catalysed by a new series of [P-O]Pd catalysts based on o-alkoxy derivatives of diphenylphosphinobenzene sulfonic acid.

Palladium catalysed copolymerisation of ethene with alkylacrylates: polar comonomer built into the linear polymer chain.

Copolymerisation of ethene and alkylacrylates is catalysed by palladium modified with di(2-methoxyphenyl)phosphinobenzene-2-sulfonic acid (DOPPBS); a linear polymer is produced in which acrylate units are incorporated into the polyethylene backbone.
