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.
