Unsaturated oils cationic polymerization

Polymerizable monomers produced by plants such as terpenes and unsaturated plant oils (Chart 1, Group A) are one of the most desired groups. Of these, terpenes are the most important class from a commercial standpoint [28]. These polymers find widespread use as tackifying agents in adhesives. The cationic polymerization of plant oils (e.g., soybean oil) is known but the resultant materials do not possess useful physical properties and therefore they are typically copolymerized with petroleum-derived monomers (e.g., divinylbenzene, dicyclopentadiene) [29-35]. 

On the other hand, the high degree of unsaturation of this type of drying oil has made it a potential monomer for polymerization into useful polymers. More recently, Li and Larock (41) reported the conversion of tung oil to solid polymers by cationic copolymerization with divinylbenzene as a comonomor. The resulting polymers have proven to be thermosetting materials with good mechanical...
