Melting and Crystallization of MC Nylon-6

Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022

Received Date: 19 July 1994
Revised Date: 18 October 1994

The influences of addition of La₂O₃ and Y₂O₃ on the crystallization and melting be-havior of MC nvlon-6 have been studied by DSC technique at a rate of 10℃/min. Both rare earth oxides increased the crvstallization temperattire T_c and decreascd the melting tempera-ture T_m of MC nylon-6,decreased the crystallinity X_c. Addition of La₂O₃ decreased the equi-librlum melting temperature T_m^o,leading to the increased crystallization rate and imperfect-ness of the crvstallization. Adtlition of Y₂O₃ increased the T_m^o, remarkedly improving the thermal stability of MC nylon-6.
