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.

标 题:Method for the synthesis of copolymers for producing polymethacrylimides
发明人：SCHERBLE JONAS; STEIN PETER; ALUPEI JULIAN C; RITTER HELMUT; SCHWARZ-BARAC SABINE
权利人:ROEHM GMBH
摘要:The invention relates to a method for producing polymethacrylimides in two steps: 1) radical copolymerization of (meth)acrylamides (A, (Me,H)HC=CHCONHR2) and alkyl(meth)acrylic esters (B) and optionally further ethylenically unsaturated monomers in the presence of an aqueous solvent. The monomers (A) include, in addition to acrylamide and methacrylamide, (meth)acrylamides that are substituted on their nitrogen group (R2<>H). The monomers (B) are the (meth)acrylic esters of secondary or tertiary alcohols, preferably tert. butylmethacrylate. 2) Thermal or catalytic reaction of the copolymers produced in 1) to polymethacrylimide or for R2<>H to N-substituted polymethacrylimides while alkenes are separated.

摘要:An in vitro and/or in vivo method of producing malonic semialdehyde (MSA) or an anion or salt thereof and/or 3-hydroxypropionic acid (3-HP) or an anion or salt thereof is provided herein. The method may comprise two steps: (1) hydrating acetylenecarboxylic acid (ACA) or an anion or salt thereof by reacting the ACA or an anion or salt thereof with an ACA-hydrating enzyme to form a reaction product comprising malonic semialdehyde (MSA) or an anion or salt thereof; and (2) reacting the reaction product comprising MSA or an anion or salt thereof with one or more oxidoreductases in an oxidation-reduction (redox) reaction to produce 3-HP or an anion or salt thereof A pair of oxidoreductases may additionally recycle a cofactor, such as NADPH or NADH. Recombinant microbes and compositions are also provided herein which may include ACA-hydrating enzymes or variants thereof, and/or one or more oxidoreductase enzymes.
