Abstract

Summary: The effects of β‐CD, partially methylated and per‐methylated β‐CDs on the crystallization behavior of P(3HB) have been investigated. All measurements, including FT‐IR spectra, WAXD, and DSC, showed that the details of interaction between P(3HB) and respective CDs were varied with the degree of methyl substitution of CDs. The crystallization of P(3HB) was enhanced by an addition of immiscible β‐CD, while it was restricted by the introduction of methylated CDs via the formation of miscible blend with di‐O‐methyl β‐CD and via the formation of an IC with tri‐O‐methyl β‐CD, respectively.
