“…Endo et al, developed diethyl ketone-based imines showing fast hydrolysis rate in atmospheric conditions [47,184,185]. They observed that, despite the imine/enamine equilibrium, mixtures with epoxy resins present pot-life larger than 1 month.…”

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.

“…They include very simple approaches, like using a weakly nucleophilic amine [44,45], and more sophisticated solutions, such as preventing the reaction of the amine with a protective group [46,47]. This will be detailed later in this review.…”

“…The curing system of imine‐based one‐component epoxy resin is composed of two steps, that is, the first step is the hydrolysis of the imines releasing amines, and the second step is the reaction of the generated amine with epoxides. We have recently reported that diethyl ketone‐based imines show a faster hydrolysis rate than industrially used methyl ethyl ketone‐ and methyl isobutyl ketone‐based imines, and one‐component epoxy resins with diethyl ketone‐based imines show good curing properties and storage stability 4–6. On the other hand, an amine‐epoxide reaction has been reported by many researchers 7–11.…”

It was demonstrated that the reaction of epoxide and imine as a latent initiator under highly humid conditions was accelerated by addition of 5‐phenoxymethyl‐1,3‐oxathiolane‐2‐thione (1). When 1 was added to a mixture of glycidyl phenyl ether and an imine, the reaction of the epoxide with an amine released from the imine became faster than was the case without 1, that is, 1 worked as a promoter of the reaction. The curing rate and initial adhesive strength of epoxy resin increased compared with that without 1. © 2004 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 42: 4276–4283, 2004

ABSTRACT:The effect of addition of methacrylate polymer into a one-component epoxy resin, containing Epikote 828 and diimine as a water-initiated hardener, was examined. Although the cured epoxy resin in the presence of methyl methacrylate-butyl acrylate (MMA-BA) copolymer was very brittle, the resin containing MMA-BA-[␥-(methacryloxy)propyl]trimethoxysilane (TMSMA) copolymer showed good mechanical and adhesive properties. The adhesive strength of the cured epoxy resin containing MMA-BA-TMSMA copolymer was much higher than that without its polymer.
