FIELD: medicine.
SUBSTANCE: group of inventions refers to medicine, namely to embodiments of a mixture of absorbable polymers, to use thereof for preparing a medical device and to a method of producing a medical device by treating said mixtures. Disclosed mixtures include a first polymer - polylactide or a lactide/glycolide copolymer (with lactide content of 70 mol. % or more) and a second polymer - poly (n-dioxanone), the minimum weight percentage of which in the mixture depends on the molar amount of polymerised lactide in the first polymer. In one embodiment, the first polymer has a unimodal molecular weight distribution (MW), and the second polymer has a bimodal distribution of MW. In another embodiment, the first polymer has a bimodal distribution of MW, and the second polymer has a unimodal or bimodal distribution of MW.
EFFECT: group of inventions provides high rate of crystallisation of the mixture of polymers, as well as improved strength, stiffness and stability of dimensions of the medical device.
