【Abstract】 By using DSC techniques,the melting behvior of nascent polyamide-66 preparedby solid state polycondensation(SSPPA66)and SSPPA66 film casted from formic acid solu-tion has been investjgated.A single melting peak for nascent SSPPA66 and double meltingpeaks for SSPPA66 film were observed.It appeared that in the SSPPA66 film there are twokinds of crystal with different crystalline structure.更多还原
