标题 :Synthesis of linear polyoxazolidinones using uretdiones as diisocyanate component
发明人：QUELL AGGELIKI; THOMAS HANS-JOSEF; ELING BEREND
权利人:BASF SE
摘要:A process for preparing a thermoplastic polymer involves reacting at least components (a) to (b), in the presence of a catalyst composition (c). Component (a) is an isocyanate composition containing at least one uretdione diisocyanate (a-i), and component (b) is an epoxide composition containing at least one diepoxide (b-i). The catalyst composition (c) contains at least one ionic liquid (c-i), preferably selected from 1-ethyl-3-methyl imidazolium bromide, 1-benzyl-3-methyl imidazolium chloride. 1-butyl-1-methylpiperidinium chloride, 1-ethyl-2,3-dimethylimidazolium bromide, 1-(2-hydroxyethyl)-3-methyl imidazolium chloride, butyl-1-methylpiperidinium acetate, or mixtures of two or more thereof. A thermoplastic polymer obtained or obtainable from the process is useful for the preparation of a fibre or a molded article or as a modifier for another thermoplastic material.

权利人:COVESTRO DEUTSCHLAND AG
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.
