摘要:A thermoplastic thiourethane polymer comprising a sequential chain of a first type of monomer covalently bonded to a second type of monomer via thiourethane linkages. The first type of monomer includes two or more thiol functional groups and the type of monomer includes two or more isocyanate functional groups. The first and second types of monomers are polymerized together in an anhydrous aprotic solvent-dissolved anionic step-growth polymerization reaction that is catalyzed by a non-nucleophillic base having a pKa greater than 7.

摘要:A polyurethane polymer and method of preparing it is described. The process requires the combination of a soluble polyol with a di- or polyisocyanate under densified fluid conditions. The process to prepare a waterborne polyurethane involves the utilization of a polyol containing ionic or latent ionic groups which must undergo preneutralization before combining with the di- or polyisocyanate under densified fluid conditions. The resulting polyurethane is substantially free of an organic solvent.

摘要:A semi-crystalline thiourethane polymer. The semi-crystalline thiourethane polymer comprises a sequential chain of a first type of monomer covalently bonded to a second type of monomer via thiourethane linkages. Each of the first type of monomer includes two or more thiol functional groups and each of the second type of monomer includes two or more isocyanate functional groups. The first and second types of monomers are polymerized together in an anionic step-growth polymerization reaction that is catalyzed by a non-nucleophillic base having a pKa greater than 7, produced by photo-initiated decomposition of a photolatent base. A method of synthesizing, and polymer jetting and stereolithography methods of manufacturing a polymer part, are also disclosed.

摘要:The invention relates to a multi-stage process for the continuous, phosgene-free preparation of (cyclo)aliphatic diisocyanates that comprises the conversion of (cyclo)aliphatic diamines into the corresponding (cyclo)alkylene biscarbamates and the thermal cleaving of the latter into the (cyclo)alkylene diisocyanates and alcohol. The urea used in accordance with the invention and also the urea employed for the preparation of urea equivalents (e.g. alkyl carbonates, alkyl carbamates) as a possible precursor for the synthesis of the (cyclo)aliphatic biscarbamates is unconditioned.

摘要:The present invention relates to polyoxazolidinone compounds, a method for the production of polyoxazolidinone compounds, comprising the step of reacting a biscarbamate compound with a bisepoxide compound in the presence of a mono-carbamate, a mono-isocyanate and/or a mono-epoxide compound as chain regulator and a suitable base having a pK b value of ≤9 as catalyst. The invention further relates to the use of polyoxazolidinone compounds with high thermal stability.
