TL;DR: In this article, the effects of long chain branching on the nucleation density enhancements and morphological evolution for polylactide (PLA) materials during shear-induced isothermal crystallization process were thoroughly investigated by using rotational rheometer and polarized optical microscopy (POM).

TL;DR: In this paper, an easy procedure was applied to prepare high-melt-strength polylactide (PLA) that involves γ-radiation-induced free-radical reactions to introduce a long-chain branched structure onto a linear PLA precursor with addition of a trifunctional monomer, trimethylolpropane triacrylate (TMPTA).

TL;DR: In this article, a series of asymmetric biodegradable poly(l-lactide) (PLLA)/poly(d-l-latide) blends with low PDLA compositions was prepared using a solution blending method, and the formation of stereocomplex (SC) crystallites in PLLA/PDLA blends was evidenced by differential scanning calorimetry.

TL;DR: In this paper, a series of long chain branched polylactides (PLA) samples with different branching degrees were used to investigate the effects of long-chain branching (LCB) on the crystallization kinetics of PLA, and the results showed that the spherulitic growth rates of the LCB PLA samples are lower than that of the linear PLA precursor.

TL;DR: In this paper, the spherulitic growth rates for the lower polylactide (PLA) layer in poly(e-caprolactone)/polylactides (PCL/PLA), poly(ethylene oxide)/poly lactide(PEO/PLA) and poly(methylene glycol)/polynactide double-layer films during isothermal crystallization at various temperatures above the melting points of PCL, PEO and PEG layers have been measured by using polarized optical microscopy (POM), with particular results compared with those for
