Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
147 words
Polyketone derived products, characterized in that they can be prepared by polymerizing a mixture of carbon monoxide and one or more olefinically unsaturated compounds having at most 20 carbon atoms in the molecule, by contacting the mixture at an elevated temperature and pressure with a catalyst composition containing a Group VIII metal, a bidentate ligand and, optionally, an organic oxidant, and with a polymeric polyol or an unsaturated rubber, where both the catalyst composition and the polymeric polyol or the unsaturated rubber are dissolved in a diluent in which the polyketone derived products to be prepared are insoluble or virtually insoluble, with the proviso that if a polymeric polyol is used in the preparation of the polyketone derived products, an organic oxidant is present in the catalyst composition used, whilst, moreover, the diluent used consists for more than 50 %vol of one or more aprotic polar compounds.
Claim 2
Dependent Claim
147 words
Polyketone derived products, characterized in that they can be prepared by polymerizing a mixture of carbon monoxide and one or more olefinically unsaturated compounds having at most 20 carbon atoms in the molecule, by contacting the mixture at an elevated temperature and pressure with a catalyst composition containing a Group VIII metal, a bidentate ligand and, optionally, an organic oxidant, and with a polymeric polyol or an unsaturated rubber, where both the catalyst composition and the polymeric polyol or the unsaturated rubber are dissolved in a diluent in which the polyketone derived products to be prepared are insoluble or virtually insoluble, with the proviso that if a polymeric polyol is used in the preparation of the polyketone derived products, an organic oxidant is present in the catalyst composition used, whilst, moreover, the diluent used consists for more than 50 %vol of one or more aprotic polar compounds.
