摘要：
A relation between tensile modulus of oriented polypropylene filled with calcium carbonate, and modified with poly(ethylene glycol) (PEG) or alkyl phenyl ether derivatives (APED) of different molecular weights was investigated. Upon stressing, voids appear in the composites material. For systems prepared with unmodified CaCO//3, the void volume increases with an increase of filler content. For systems containing modified CaCO//3, the void volume is smaller than the one of the reference material and decreases with an increase of PEG or APED molecular weights (which range from 400 to 4000 for PEG).
