Abstract: The semi-crystalline dendritic polymers were prepared from the dendritic polyetheramide with hydroxyl end-groups by being grafted with myristoyl chloride, palmitoyl chloride, and octadecyl isocyanate in different substitution degrees, respectively. The thermal properties and the crystallization behavior of the resulted samples were studied by differential scanning calorimetry and optical microscopy, respectively. The experimental results have shown that the length of the alkyl chain attached and substitution degree have apparent influences on the glass 4 transition temperature, melting enthalpy and the size of crystallite.
