摘要： Bioerodible, thermoset, covalently crosslinked, elastomeric poly(ortho ester)s are disclosed. These materials are comprised of polymer chains that are interlocked in a covalent, three dimensional network which imparts dimensional stability. Use of these thermoset, covalently crosslinked materials as a drug delivery device is also disclosed.

摘要： Linear alternating copolymers of carbon monoxide and an unsaturated bicyclic carboxylic acid compound are produced in the presence of a catalyst composition formed from a palladium compound, an anion of certain strong acids and a bidentate ligand of nitrogen. When the bidentate ligand is a bidentate ligand of phosphorus and an ethylenically unsaturated hydrocarbon is also present, a mixture of polymers is produced which includes the linear alternating copolymer.

摘要： A process for preparing linear, alternating interpolymers of olefins and carbon monoxide (polyketones) comprises reacting carbon monoxide with one or more olefins in the presence of a catalyst prepared by reacting a source of palladium, with a bidentante amine, phosphine, arsine or stibine and a anion of a anion having the formula: ##STR1## wherein the R groups are independently selected from C.sub.1 to C.sub.6 alkylene groups, ortho-phenylene or biphenylene groups or groups having the formula: ##STR2## or substituted derivatives thereof. The process is characterized by being carried out in the presence of a quinone e.g. benzoquinone.

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.
