“…As mentioned above, among the numerous studies on bubble motion and interaction, the experiments mainly concern water or other aqueous solutions such as glycerol, carboxymethyl cellulose, and others. Hydrocarbon resin (HR), a sort of hydrocarbon polymer obtained from polymerizing C9 fraction (a low‐grade byproduct in ethylene production), is one of the foremost tackifying resins 37 . As a significant fine chemical, HR is widely applied in coatings, adhesives, hot melts, paints, varnishes, construction industries, foods, rubber tires, and so forth 38,39 .…”
