Supported metal halides and metal halide 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 solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5Â C. to 170Â 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 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.

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. degree. C. to 170. degree. 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.

Hercules Incorporated - Wilmington DE
International Classification:
C08F 422 C08F 1212
US Classification:
526130
Abstract:
Metal oxide solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomer (e. g. , styrene based monomers), C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5. degree. C. to 170. degree. 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.
