초록 Nanocomposites of poly(butylene terephthalate) (PBT) with the organoclay C12PPh-MMT were prepared using in-situ intercalation polymerization. Hybrids with various organoclay contents were processed for fiber spinning in order to examine their thermal behavior, tensile mechanical properties, and morphologies for various draw ratios (DRs). The thermal properties (Tg, Tm, and TDi) of the hybrid fibers were found to be better than those of pure PBT fibers and were unchanged by variation of the organoclay loading up to 2 wt %. However, these thermal properties remained unchanged for DRs ranging from 1 to 18. Most clay layers were dispersed homogeneously in the matrix polymer, although some clusters were also detected. The tensile properties of the hybrid fibers increased gradually with increasing C12PPh-MMT content at DR = 1. However, the ultimate strengths and initial moduli of the hybrid fibers decreased markedly with increasing DR.
