Alkyd resins synthesized from postconsumer PET bottles

Alkyd resins based on hyperbranched polyesters and PET waste for coating applications

“…Glycolysis, hydrolysis, methanolysis, aminolysis and ammonolysis are the most recycling strategies for this material [3][4][5][6][7][8]. Production of specialized products such as saturated and unsaturated polyester resins, polyurethanes, coating materials and additives, using PET waste, has been investigated [9][10][11][12][13][14][15][16][17].…”

“…Long oil alkyd resins from phthalic anhydride, depolymerization product of PET waste, glycerin, sunflower oil fatty acids and glycol were prepared by Güclü and Orbay [15]. Film properties and thermal stability of these alkyd resins were better than the properties of reference alkyd resin.…”

Effect of surface modified TiO2 nanoparticles on thermal, barrier and mechanical properties of long oil alkyd resin-based coatings

“…Alkyd resins based on non-toxic, biodegradable, multifunctional, low cost, physically and chemically stable and eco-friendly renewable resources such as vegetable oils show properties comparable with properties of products based on petroleum, and therefore have found their industrial application in paints and surface coatings [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Especially interesting low cost vegetable oil is soy bean oil, which has balanced composition of unsaturated and saturated fatty acids and it can reduce yellowing and oxidative degradation of resin [2,[16][17][18][19].…”

High performance alkyd resins synthesized from postconsumer PET bottles

“…Most of the reported PET glycolyzates for the synthesis of alkyd resins were difunctional [19,20]. Difunctional components provide lower branching and, thus, lower molar masses of alkyd resins and, consequently, insufficient mechanical, drying, chemical resistance properties, etc.…”
