摘要

The effect of α phase nucleating agent (NA) 1

3:2

4-bis(3

4-dimethylbenzylidene) sorbitol (DMDBS) on crystallization and physical properties of polypropylene/calcium carbonate (PP/CaCO3) composites has been comparatively investigated. Compared with binary PP/CaCO3 composites

in which CaCO3 exhibits weak heterogeneous nucleation

inconspicuous reinforcement and toughening effects for PP

the introduction of a few amounts of DMDBS induces a great increase of the degree of crystallinity. Largely improved tensile properties

fracture toughness at relatively higher temperature and heat deformation temperature (HDT) are observed for DMDBS nucleated PP/CaCO3 composites.
