摘要： Linear alternating polymers of carbon monoxide and at least one ethylenically unsaturated hydrocarbon, useful as premium thermoplastics, are produced by contacting the carbon monoxide and hydrocarbon reactants under polymerization conditions in the presence of a catalyst complex of hydrocarbylpalladium halide and a bidentate ligand of phosphorus. The catalyst complex is produced by contacting a complex of palladium dihalide and the bidentate phosphorus ligand with a tetrahydrocarbyltin.

摘要： A process for the hydroformylation of less reactive olefins with hydrogen and carbon monoxide in the presence of a Group VIII-metal hydroformylation catalyst which has been modified by a ligand of formula L(OR.sup.1) (OR.sup.2)(OR.sup.3), wherein L represents P or As and R.sup.1, R.sup.2 and R.sup.3 are similar or dissimilar aryl groups provided that at least one of R.sup.1, R.sup.2, R.sup.3 is a group ##STR1## wherein Q represents a group ##STR2## or a group ##STR3## wherein R.sup.4 is an optionally fluorine-substituted hydrocarbyl group, R.sup.5 is H or R.sup.4, R.sup.6 is H or an inert substituent on the metal and/or the para position of the ring, X is O or S and n is 0 or 1 and R.sup.7 represents a hydrogen atom or an inert substituent. Less reactive olefins such as limonene can be hydroformylated with very good results.
