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.

标 题:Irreversible immobilization of enzymes into polyurethane coatings

摘要:A method of irreversibly immobilizing an enzyme in a polyurethane and an enzyme-containing polyurethane having a degree of immobilization of the enzyme of approximately 100%. The synthesis of waterborne polyurethanes in the presence of enzyme has enabled the irreversible attachment of the enzyme to the polymeric matrix. The distribution of immobilized enzyme as well as activity retention are homogeneous within the polyurethane. Decreasing ECC hydrophobicity, via the use of a less hydrophobic polyisocyanate prepolymer during polymerization, significantly enhanced the intrinsic activity of the ECC.

摘要:A method of making polyesters and polyurethanes from biomass-derived polyols. The polyol is biomass-derived and has the structure:wherein dashed bonds are single or double bonds and R is selected from the group consisting of —OH and â•?O. Polyurethanes are made by reacting the polyol with a diisocyanate. Polyesters are made by reacting the polyol with a dicarboxylic acid.
