The non-isothermal crystallization behaviour of high purity b-phase and a-phase polypropylene (PP) and their calcium carbonate-รlled composites was investigated by means of di โ erential scanning calorimetry. High purity b-PP polymer was prepared by adding an e โ ective b-nucleator consisting of equal
The crystallization studies revealed that the high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) formed strong cocrystalline mass when they were melt blended in a single screw extruder. The progress of crystallization was observed through a small-angle light scattering inst
## Abstract Calcium carbonate/lowโdensityโpolyethylene (LDPE) nanocomposites have been prepared by melting blend with twinโscrew extruder. The mechanical properties of composites and the dispersion of the nanoparticles were studied. The reinforcement mechanism was discussed. The results show that n
