Phase structure and deformation-strength properties of mixtures of polylactic acid with flexible-chain polyesters

Polylactic acid (polylactide) is the most widely used biodegradable polymer. To eliminate its brittleness and low flexibility, various approaches to plasticization are used, in particular, compounding with more flexible polymers. The possibilities of plasticizing polylactide polycaprolactone polybutylene adipate/terephthalate by mixing polymers a solution subsequent film formation have been studied as well thermophysical mechanical characteristics resulting materials studied. effect plasticizer additives on phase structure decrease crystallinity crystallite perfection was found. Thus, amorphization observed. flexibility increased, evidenced increase relative elongation under tensile strain films.
