AbstractNoncrosslinking linear low-density polyethylene-grafted acrylic acid (LLDPE-g-AA) was prepared by melt-reactive extrusion in our laboratory. The thermal behavior of LLDPE-g-AA was investigated by using differential scanning calorimetry (DSC). Compared with neat linear low-density polyethylene (LLDPE), melting temperature (T-m) of LLDPE-g-AA increased a little, the crystallization temperature (T-c) increased about 4degreesC, and the melting enthalpy (DeltaH(m) ) decreased with an increase in acrylic acid content. Isothermal crystallization kinetics of LLDPE and LLDPE-g-AA samples were carried out by using DSC. The overall crystallization rate of LLDPE was smaller than that of grafted samples. It showed that the grafted acrylic acid monomer onto LLDPE acted as a nucleating agent. Crystal morphologies of LLDPE-g-AA and LLDPE were examined by using SEM. Spherulite sizes of LLDPE-g-AA samples were lower than that of LLDPE. (C) 2002 Wiley Periodicals, Inc.
