摘要:The present invention relates to a method of synthesis of a biodegradable polyurethane foam, comprising the following steps: i) mixing of at least one aliphatic isocyanate bearing at least two isocyanate groups with at least one saccharide in weight ratio of from 1:1 to 30:1 to form a saccharide-isocyanate precursor; ii) homogenization of the saccharide-isocyanate precursor from step i) with 20 to 70 % (w/w) of at least one biodegradable aliphatic polyester-ether polyol having molecular mass in the range of from 0 to 10 000 g/mol and hydroxyl number from 10 to 100 mgKOH/g, 1 to 5 % (w/w) of water, and 1 to 10 % (w/w) of at least one blowing agent other than water, related to the total weight of the resulting mixture; iii) foaming of the homogenized mixture from step ii) at the temperature of from 20 to 100 °C, resulting in the biodegradable polyurethane foam comprising incorporated saccharide. The invention further relates to a biodegradable polyurethane foam obtainable by this method, to a biodegradable polyurethane foam-based material for saccharide-cleaving enzyme production and to the use thereof.

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 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.

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.
