Composites　based　on　thermal　liquid　crystalline　polymer　(TLCPa)　and　polyamide　6　(PA6)　were　prepared　using　a　solution-mixing　technique　in　this　study.　Differential　scanning　calorimetry　(DSC),　thermogravimetry　analysis　(TGA),　wide　angle　X-ray　diffractometry　(WAXD)　and　polarizing　optical　microscope　(POM)　were　applied　to　study　the　compatibility,　thermal　stability　and　crystallization　behaviour.　The　addition　of　TLCPa　enhanced　the　thermal　stability　of　PA6.　The　degradation　onset　temperature　of　composites　with　30%　TLCPa　in　weight　increases　nearly　27C　rather　than　pure　PA6.　This　is　due　to　the　increase　of　miscibility　induced　by　the　intermolecular　interactions　between　these　polymers.　Crystallization　behavior　revealed　that　the　TLCPa　inhibited　the　orientation　of　polymer　chain　resulting　in　the　decreases　in　crystallinity,　but　no　effects　on　crystal　modification　manifested　also　by　XRD　spectra.　XRD　spectra　of　amorphous　state　appeared　when　the　addition　of　TLCPa　over　40%　in　weight.　Crystal　morphology　refinement　was　observed　by　polanized　optical　microscopy　(POM).
