Synthesis of unsaturated polyester resins based on rosin acrylic acid adduct for coating applications

Recent Progress in Sustainable Polymers Obtained from Cyclic Terpenes: Synthesis, Properties, and Application Potential

“…[102] ChemSusChem 2015, 8,2455 -2471 www.chemsuschem.org this, for example, the monomers acrylopimaric acid (APA) and maleopimaric acid (MPA), which are derived from abietic acid, can be utilized (Figure 7). [107] Examples for such structuresa re polyketones, [108] photoactive polyamide-imides, [109] or polyamides, [110] which are all obtained by corresponding polycondensation reactions (Figure 7). Similar 17-and bileacid based polycondensation products have also been prepared;t hey have been reviewed elsewhere in detail.…”

Synthesis, structure and properties of poly(ether-urethane)s synthesized using a tri-functional oxypropylated glycerol as a polyol

“…Currently, polymers are prepared from components, which are derived from petroleum [5,6]. Renewable substances proposed for the synthesis of polymers are, for example, vegetable oils (e.g., linseed oil, sunflower oil, palm oil, cotton oil, soybean oil, tung oil, cashew nut oil [5][6][7][8]), glycerol and its derivatives [9,10], terpenes [11] and rosin [12,13]. The bio-based components, which can be used as a polyols in the synthesis of polyurethanes, are, for example, castor oil [14], polyricinoleate diol [15], hydroxylated soybean oil [6,16], hydroxylated hemp seed oil [17] and polyglycerols [18].…”

Monomers and Resulting Polymers from Biomass

“…The ability to produce polyesters and polyurethanes from rosin has been demonstrated [154][155][156]. Jin et al used maleic-modified rosin to produce two kinds of rosin-based polyester polyols by esterification of the anhydride species with either diethylene glycol or ethylene glycol [154].…”

“…Unfortunately, little work has followed up on the early study, leaving questions about the mechanical properties of the foam. Unsaturated polyesters were produced by Atta et al using acrylic-acid-substituted rosin, maleic anhydride, and propylene or ethylene glycol [156]. The resulting polymers had only moderate molecular weight (5 kDa), but could be cross-linked [156].…”

“…Unsaturated polyesters were produced by Atta et al using acrylic-acid-substituted rosin, maleic anhydride, and propylene or ethylene glycol [156]. The resulting polymers had only moderate molecular weight (5 kDa), but could be cross-linked [156]. Combining the unsaturated polyesters with styrene and curing the system led to materials with good mechanical properties and good resistance to both acid and alkali environments [156].…”
