This review highlights both the various polymers grafted to alkyd resins reported in the literature and the different routes to synthesize these alkyd hybrids. Alkyd resins were discovered in the mid-1920s. Then, they quickly found a prominent place among coatings and paint binders thanks to their numerous advantages such as good heat resistance, excellent gloss, and low cost. Nevertheless, in the 50s, the emergence of new synthetic polymers with better properties (chemical resistance, mechanical and thermal properties) such as epoxy, acrylic or polyurethane, weakened the position of the alkyd resins among coating industry. Nowadays, due to global issues such as health and environmental concerns, research focuses on biobased polymers. Since, alkyd resins are mainly biobased, they have gained increasing attention in the last decade. Nevertheless, the issue of using volatile organic compounds (VOC) and the urge of replacing them, have led to the development of new synthetic routes. Moreover, in order to enhance alkyd properties and bridge the gap with new materials, other polymers such as epoxy, acrylates, polyurethanes or siloxanes were used to form alkyd hybrids. Hence, the different strategies to perform alkyd hybrids are detailed and discussed in this review. Furthermore, composites made with alkyd hybrid matrix are presented. Finally, the perspectives about the future developments of alkyd hybrids and the most promising hybrids are discussed.

Modification of existing paints and varnishes based on alkyd and melamine alkyd resins as well as creation of new film formers with the help of functionalized oligomers in order to improve the properties of materials during their operation was carried out. Liquid oligobutadiene rubber with end hydroxyl groups, HTPB trend mark was used . Pentaphthalic varnish PF-060 and melamine-formaldehyde resin K-421-02 was modified by triisocyanate oligobutadiene rubber based on trimethylolpropane and isophorone diisocyanate resin in different ratios. Analysis of the FTIR spectra of the developed paints and varnishes showed that the process of polymerization in a thin film in air forms a spatially crosslinked polymer and passes through the stage of formation of branched soluble polymers, followed by copolymerization of components with oxygen and formation of structured solid polymer. The optimal content of rubber in the modified paints and varnishes was estimated. For alkyd varnish PF-060 it equals 10 wt.% and for melamine-formaldehyde resin K-421-02 is in the range 7-10 wt.%. Addition of triisocyanate accelerates the drying process of coatings on air, high values of surface hardness, adhesion, resistance to bending and water absorption were also received. Developed modified paints and varnishes are characterized by increased viability, shelf life of more than 6 months, homogeneity. Proposed scheme allows to obtain transparent coatings with high physical and mechanical characteristics and can be recommended for practical use in various coating technologies.
