Title:
PROCESS FOR PRODUCING HIGH-SOFTENING-POINT AROMATIC PETROLEUM RESIN AND PRINTING INK CONTAINING THE PETROLEUM RESIN
Document Type and Number:
WIPO Patent Application WO/2002/014392
Kind Code:
A1
Abstract:
A process for producing a high-softening-point aromatic petroleum resin having satisfactory solubility in nonaromatic solvents. The process comprises polymerizing a fraction obtained by petroleum pyrolysis and having a boiling point range of 140 to 220°C with turpentine oil having a diene value of 20 cg/g or higher in the presence of an acid catalyst.
