Epoxy acrylic copolymer graft composition

From the data generated so far, an attempt was made to determine the epoxy-acrylic graft copolymer composition. 

Both paints and adhesives are commonly formulated as polymer blends or grafts. In fact, some compositions resemble semi-IPN s or AB crosslinked copolymers (Section 8.7). For example, epoxy adhesive resins are often cured with polyamides (Bikerman, 1968). The product is tougher than materials cured with low-molecular-weight amines, possibly because of a separate amide phase in this AB crosslinked copolymer. A more complex molecular architecture is exhibited by the alkyd resins common in oil-based paints (Martens, 1968, Chapters 3 and 4). The major component is a polyester, which often forms a network structure on drying. The polyester component is reacted with various drying oils, such as linseed oil or tung oil (Martens, 1968, Chapters 3 and 4). These oils form an ester link to the polyester structures and also polymerize through their multiple double bonds. Latex paints always contain thickeners, such as cellulosics, poly(acrylic acid), casein. 

Number of grafted copolymers were prepared by the ozonization and grafting technique. Polyolefins, PE and PP, were grafted with fluorinated acrylates to obtain fluorine content between 11% and 25% that highly modified their properties. Likewise, PE and PVDF have been grafted with various acryhc monomers with the aim to improve their adhesive properties. From these products, it has been possible to attach composite materials, based on epoxy resins, to PE or PVDF. The main copolymers prepared according to this technique are summarized in Table 1.
