A series of polyoxymethylene (POM)/poly(butylene succinate-co-butylene adipate) (PBSA) alloys were prepared by melt blending method.Intermolecular interactions

miscibility and crystallization behavior of POM/PBSA blends were studied using FTIR

dynamic mechanical analysis (DMA)

differential scanning calorimetry (DSC)

polarized light microscopy (PLM) and WAXD.The results show that intermolecular hydrogen bonding forms between carbonyl groups of PBSA and hydroxyl groups of POM

which increases the miscibility between PBSA and POM.Meanwhile

melting and crystallization temperatures of POM decrease with addition of PBSA.However

it is worth noting that lower content of POM in alloys has great influence on PBSA crystallization.Incorporation of 15 wt% of POM shows significant nucleating effect for PBSA and promotes its crystallization

resulting in reduced lattice spacing.In addition

the miscibility between POM and PBSA is dependent on the PBSA content.Miscibility of POM/PBSA alloys improves with increasing PBSA content.But the addition of PBSA does not modify the crystal structure of POM.
