    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 DEG C to 170 DEG 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 translation: 使用金属氧化物固体酸作为用于聚合包含纯单体(例如苯乙烯基单体),C5单体和C9单体中的至少一种的进料流的催化剂以产生烃树脂。 在使用之前,可以从固体酸催化剂中除去自由相关的水。 可以制备在约5℃至170℃范围内具有软化点(环和球)的树脂。 这些催化剂具有优于传统的Friedel-Crafts聚合催化剂的优点,因为酸性部位是固体的组成部分。 固体酸催化剂是相对非危险的,可重复使用的催化剂,其消除或至少减少所得树脂产物与酸残基或副产物的污染。
