标 题 :Rhodium based catalysts for the synthesis of 1,4-dienes
发明人：SU A
权利人:DU PONT
摘要:Improved catalysts are provided for the synthesis of 1,4-dienes from Alpha -monoolefins and conjugated dienes. The catalysts are rhodium (III) salts in combination with amides, phosphoramides, phosphine oxides, or water. The improved catalysts allow control of the trans-cis ratio of the 1,4-diene formed and are operable at useful rates in a wide range of solvent systems, both protonic and aprotic.

摘要:The invention relates to a process for the anionic polymerization and copolymerization of vinyl, dienic and heterocyclic monomers. According to the invention, the process consists in carrying out the reaction in the presence of an initiator consisting of a molecular combination of an alkali metal amide and the salt of the same alkali metal with at least one hydroxylic compound and in the absence of solvent. The initiator can be prepared by intimately mixing its constituents or in the presence of a solvent of low polarity which is subsequently evaporated off, or in situ in the monomer. Application to the synthesis of special or widely used polymers and copolymers.
