Acrylonitrile butadiene styrene

A series of blends of Acrylonitrile-Butadiene-Styrene (ABS) and Polycarbonate (PC)

were prepared and some of their thermal and mechanical properties were determined.

The Young’s modulus changed gradually and monotonically with the polycarbonate content.

This effect was tentatively explained as the antiplasticization of the PC which is ascribed to the chain mobility,

which permits the PC chains to pack more tightly, to the secondary cross-linking between the PC chains,

or to the secondary attachment of bulky side-chains to the PC,

thus producing steric hindrance to the rotation of the PC main chains.

The experimental values found for the impact strength were intermediate between those of the neat polymers,

depending upon the dispersed rubber particles of butadiene in the matrix of SAN (Styrene-Acrylonitrile),

and the dispersed PC particles which generally make the ABS more brittle.

A maximum value of about 88 KJ/m2 for the impact strength was observed for the blend with 90% PC.

This may be attributed to the strong polymer-polymer interactions for this particular composition.

The variations in the heat deflection temperature HDT and the Vicat softening point with the blend composition were very similar,

and allowed us to assume that the phase inversion between the matrices of the two polymers takes place at 50% PC.

The morphology of the blends revealed by SEM observation, show a co-continuous structure.
