Title:
【発明の名称】炭化水素樹脂の製造のための触媒としての固体酸
Document Type and Number:
Japanese Patent JP2001509185
Kind Code:
A
Abstract:
Fluorinated solid acids and supported fluorinated solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomer, C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the fluorinated solid acid catalyst and/or supported fluorinated solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5° C. to 170° C. can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerization catalysts since the acid sites are an integral part of the solid. The fluorinated solid acid catalysts and supported fluorinated solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or by-products.
