Abstract
PURPOSE: To obtain a hydrocarbon resin, suitable for an adhesive mass or tackifier, by the cationic polymerization of a monomeric mixture containing 1,3-pentadiene, butene, α-methylstyrene and 1,3-butadiene in a specific proportion.
CONSTITUTION: 100pts.wt. monomeric mixture containing 30W75wt% 1,3-pentadiene, 5W40wt% butene, 10W40wt% α-methylstyrene and 0W15wt%, preferably 2W 10wt%, 1,3-butadiene at a weight ratio between the butene and the α-methylstyrene of preferably 1/2.5W2.5/1 is subjected to the cationic polymerization in the presence of preferably 50W500pts.wt. diluting agent, e.g. an aromatic hydrocarbon, and a Friedel-Crafts catalyst, e.g. AlCl3, to give a hydrocarbon resin having a softening point of preferably 60W140°C.
