  • Process for preparing light colored petroleum resins and resins produced thereby
    Patent number: 4562233
    Abstract: Petroleum resins of lightened color while retaining satisfactory melting point and compatiblity are provided by a process which comprises heat soaking a petroleum cracking or reforming fraction containing cationically polymerizable hydrocarbons and from 2 to more than 0.5 weight percent of cyclodienes until the cyclodiene content is no more than 0.5 weight percent distilling said heat soaked petroleum fraction and polymerizing said distilled petroleum fraction in the presence of a polymerization catalyst.
    Type: Grant
    Filed: January 14, 1985
    Date of Patent: December 31, 1985
    Assignee: Exxon Research & Engineering Co.
    Inventors: Augustus B. Small, Vincent L. Hughes, Francisco M. Benitez
  • Aromatic high softening point petroleum resins and process for its preparation
    Patent number: 4558107
    Abstract: High softening point, i.e. greater than 140.degree. C., aromatic petroleum resins are prepared by polymerizing with an AlCl.sub.3 catalyst an unsaturated hydrocarbon mixture of one part of (1) a feedstock fraction obtained from the thermal cracking of petroleum boiling in the range of 135.degree.-220.degree. C. and principally composed of aromatic substituted olefins, e.g. styrene and its derivatives and indenes and its derivatives and from 0.3 to 1 part by weight of (2) oligomers of cyclopentadiene.
