Abstract
This paper studies the non-isothermal crystallisation kinetics of polyamide 66 (PA66) and thermal liquid crystal polymer (TLCP) in situ composites with contents of TLCP is 1 wt.% by differential scanning calorimetry (DSC) at various cooling rates. The results show that TLCP acts as nucleator for PA66 matrix accelerating the crystallisation. It is speculated, from Avrami exponent and Liu method, that there is a strong hydrogen bonds between -NH-, -CO- groups of PA66 and -COOH and/or -OH groups of TLCP. Kissinger method is employed to obtain the activation energy of the crystallisation process and the results indicated that the addition of TLCP may entice the crystallisation of PA66 matrix. 10 Refs.
