“…Epoxy resins are known to form covalent crosslinks with cellulose based fibers via hydroxyl groups [8,16]. Furthermore, the cationic ring opening polymerization of epoxides should facilitate the incorporation of cellulose due to an activated monomer (AM) mechanism [17,18]. Based on the AM mechanism, Dillman et al recently reported the integration of different types of alcohols [19] and Broomfield et al noted the presence of water [20] during the cationic polymerization of epoxides.…”

“…But when used in their benzyl form, benzyl cations are the true initiating species and benzyl groups are incorporated into the growing chains. Their use has been reported in the polymerization of a number of epoxy monomers [108,[286][287][288][289][290].…”

“…These observations demonstrate that the influence of alcohols on cationic polymerization is a rather complex phenomenon that depends on a number of parameters besides the promotion of the AM mechanism. They include the structure of the alcohol [287,409] as well as the properties of the initiator (e.g. the reduction potential of the onium salt [404][405][406]).…”

Recent advances in macromolecular chemistry have revolutionized the way we perceive the synthesis of polymers. Polymerization, to be modern, must be "controlled", which usually means capable of producing macromolecules of well-defined structure. The purpose of this review is to examine how the chemistry of epoxy resins, an almost century-old chemistry, is also involved in this movement. Epoxy resins are characterized by both the flexibility of implementation and the qualities of the polymers obtained. Key materials in health-, mobility-and energy related technologies, these resins are heavily present in high-performance composites, electronic boards, adhesives and coatings. Currently, a large number of resins and hardeners are available on the market or described in the literature and an interesting point is that almost any combination of the two is possible. Common to all these recipes and processes is that a liquid (or soluble) resin at some point becomes insoluble and solid. It is very important to know how to manage this transition, physically known as the gel point, as it is the point after which the shape of the object is irreversibly set. Taking into account the variety of epoxy polymerization processespolyaddition, anionic or cationic polymerization-we detail a number of methods to program the occurrence of the gel point and how this type of control affects the structure of the growing network.

“…Recently, Hartwig [53] has examined the effect of different diols on the photochemically and thermally induced cationic polymerization of 3,4-oxiranecyclohexylmethyl-3Ј,4Ј-oxiranecyclohexane carboxylate, i.e. a dioxirane monomer.…”
