摘要: Chain entanglements and the entanglement degree determine many processes behaviors of polymers. In this work, poly(l-lactide) acid (PLLA) samples with markedly decreased were obtained via a freeze extraction method kinetics recovery process freeze-extracted was monitored by dynamic rheology approach. The crystallization PLLA further studied polarized optical microscope, which revealed that greatly influences lower or disentanglement conducive to melt-crystallization PLLA. spherulites grew faster in partially disentangled melt than well entangled melt.
