our colleagues from the institute of microbiology receive l and dl lactic acid, and we are here, and nstitute of physical and chemical problems of the belarusian state university, and we obtain the monomer lactitol cyclic ester and based on it. ah. scientists have learned how to obtain polymers with a good mass, molecular weight with good physicochemical properties. one of the most promising biodegradable polymers, scientists tell us. it is derived from cornstarch. polylaxide , this plastic decomposes under the influence of water, but it is worth noting that it does not dissolve in water, namely, it slowly decomposes in its presence. here you see samples. it's a policy-based film. yes, as you can see, it is quite strong, that is, according to its properties are similar to those plastics that we constantly see in packaging. we did a study of its hydrolysis, that is, how it decomposes under the action of water. here is a sample after one day, you can see that it has turned white and deformed. this is due to the fact that we carried out the process at an elevated temperature of 60 °, sin
