Star-shaped biodegradable poly(L-lactide)s are perspective materials with tailored properties and degradation rates which can be controlled by number and length of the arms. Star-shaped 6-arm poly(L-lactide)s with arm lengths from 10 to 50 units were synthesized by ring-opening polymerization and studied by NMR, GPC and DSC. The effect of arm length on electrospinning of the star-shaped polymers was demonstrated. Structure of non-woven materials based on star-shaped PLLA and its mixtures with linear high molecular weight PLLA and PEO was studied.
