RAPID COMMUNICATION: Hydrocarbon resin/polymer blends as precursors

of lustrous carbon (in English)

Polimery 2005, No 3, 216



Summary

Ternary hydrocarbon resin/expanded polystyrene/poly(vinyl chloride) (HR/EPS/PVC) blends and hydrocarbon resin/expanded polystyrene/polycyclic aromatic hydrocarbons (HR/EPS/PAH) were prepared. Softening point and lustrous carbon yield of the blends were studied to evaluate their applicability as lustrous precursors for molding sands manufacturing. The softening points of the blends increased while the lustrous carbon yield showed a flat maximum with increasing of poly(vinyl chloride) content. Both softening point and lustrous carbon yield decreased with increasing temperature of the blending.


Key words: hydrocarbon resin, expanded polystyrene, poly(vinyl chloride), polycyclic aromatic hydrocarbons, blends, lustrous carbon, softening point
