<p>A heat polymerization process to produce broad spectrum hydrocarbon resins involving bringing together in a feed stream, a double bond containing material such as styrene; mineral spirits, and an antioxidant, heating the feed stream in a reaction zone at a temperature range of from 450<o>F to 600<o> F and at a pressure range of 150 to 275 p.s.i. while moving the feed stream in a plug flow reactor at a rate of from 2400-5000 pounds per hour through the reaction zone, and removing the resultant polymer from the reaction zone. The double bond containing a material is styrene. In an alternative form, dicyclopentadiene is also added to the feed stream. Also, a peroxide catalyst may be used.</p> |
