权利人:COVESTRO DEUTSCHLAND AG
摘要:The invention relates to a method according to claim 1 for the commercial implementation of a pyrolysis, and to pyrolysis devices for the pyrolysis of pyrolysis stock used in this method. The pyrolysis stock contains a polymeric compound having at least one structural polyurethane unit of the formula (I), wherein Q is a hydrocarbon group with 2 to 8 carbon atoms, preferably 3 to 8 carbon atoms, and n represents a number from 2 to 4, most preferably 2, and -* represents a covalent bond to the polymer backbone. The method and the pyrolysis device according to the invention allow, even with higher compounds of pyrolysis stock an amount of pyrolysis product to be obtained that contains cleavage products which can be reused for the synthesis of polyurethane-containing material.

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.

摘要:Disclosed is a process for production of a cycloaliphatic carbonate from a diol, triol or polyol and a carbon dioxide source, such as a dialkyl carbonate. Said process is performed in a solvent-free medium using a N-heterocyclic carbene or N-heterocyclic carbene complex as catalyst. Said N-heterocyclic carbene or carbene complex is preferably attached to a lipase. Said process comprises preferably a transesterification step and a thermal disproportionation step and yielded cycloaliphatic carbonate is in preferred embodiments a monocyclic carbonate having a five-membered or a six-membered ring.
