The　laboratory　synthesized　thermotropic　liquid　crystalline　polyamide(TLCP)　was　solution-blended　with　polyamide　6(PA6)　with　different　contents.　The　effects　of　content　of　TLCP　on　the　compatibility　was　investigated　by　Ubbelohde　Viscometer,　DSC,　FT-IR　and　SEM.　Thermal　analyses　demonstrate　that　the　addition　of　TLCP　decreases　the　melting　temperature　of　PA6,　exhibiting　the　compatibility.　FT-IR　clearly　identified　a　specific　intermolecular　interaction　between　PA6　and　TLCP　due　to　the　similarity　in　their　structures.　Particles　coprecipitated　from　the　solutions　were　manifested　by　SEM　that　as　TLCP　content　is　above　5%　the　interface　becomes　ambiguous.　When　TLCP　content　is　up　to　40%,　the　morphology　is　homogenous　without　obvious　phase　separation　due　to　strong　molecular　interactions.　Characterizations　on　blends　support　the　idea　that　the　incorporation　of　hydrogen　bond　interaction　could　induce　the　compatibility　of　the　blends,　of　which　components　are　in　procession　of　the　same　amide　group　in　the　molecular　structure.
