Abstract
Process for preparing straight, alternate polymers based on carbon monoxide and at least one olefin, which comprises causing carbon monoxide and the olefin to react in the presence of: (a) a catalyst of general formula (I): [Pd(chel)(chel')]++[A-].sub.2 (I) wherein chel and chel', which may be the same, or different from each other, represent a bidentate chelating agent and A- stands for an anion of an acid having a pKa smaller than 6; and (b) optionally, an organic oxidizer agent.
Claims19
Process for preparing polymers based on carbon monoxide and at least one olefin, which comprises reacting carbon monoxide and the olefin in the presence of a solvent, and:
- (a) a catalyst of general formula (I):
- [Pd(chel)(chel')].sup.++ [A.sup.- ].sub.2 (I)
- wherein chel and chel', which are the same, or different from each other, represent a nitrogen or phosphorus containing bidentate chelating agent and A.sup.- represents an anion of an acid having a pKa smaller than 6;
- without or with
- (b) an organic oxidizer agent.
The process of claim 22, wherein the chel is a nitrogen containing bidentate chelating agent or a phosphorus containing chelating agent and wherein chel' is a nitrogen containing chelating agent other than chel.
