Isothermal melt crystallization of poly( L-lactide ) (PLLA) has been studied in the temperature range of 90 to 135ΠC. A maximum in crystallization kinetic was observed around 105ΠC. A transition from regime II to regime III is present around 115ΠC. The crystal morphology is a function of the degree
## Abstract The spherulitic morphology of pure poly(Lβlactide) (PLLA) was investigated with polarized optical microscopy as a function of the crystallization temperature and molecular weight. After being melted at 210Β°C for 3 min, samples were cooled quickly to designated temperatures for isotherma
