An ambient-cured coating film obtained via a Knoevenagel and Michael addition reactions based on modified acetoacetylated castor oil prepared by a thiol-ene coupling reaction

Organic–inorganic hybrid coating materials derived from renewable soybean oil and amino silanes

“…[1][2][3][4] Vegetable oils, as renewable resources, have unique chemical structures containing hydroxyls, esters, unsaturated sites, and other functional groups, and these can be modied to make low molecular weight polymeric materials for a range of versatile applications. [5][6][7][8][9] Acetoacetyl chemistry is interesting to use to prepare thermoset resins because acetoacetate functional groups can react with various groups, [10][11][12][13] including aldehydes, 14 isocyanates, 15 acrylates, 16 and amines. 17 Although many thermoset resins have been prepared using acetoacetate chemistry and amines, only a few studies have been reported on the synthesis of biobased coating materials.…”

Click chemistry for the synthesis of biobased polymers and networks derived from vegetable oils

“…158 For coating applications, polyfunctional acrylates from soybean oil have been achieved, 159 and acetoacetate-modified castor oil and soybean oil to synthesize ambient curable films when reacted with amines, 160,161 aldehydes or acrylates. 162 Furthermore, Upshaw and co-workers successfully functionalized mercaptanized soybean oil with hydroxyl, amine, isocyanate, isothiocyanate, epoxy, and silane terminal groups by TEC for applications such as foams, adhesives, coatings sealants, and elastomers. In a fascinating recently published study, biobased internal emulsifiers were synthesized using CO and cysteine derivative via TEC and used to obtain super tough WPUs.…”

Dynamic reversible adhesives based on crosslinking network via Schiff base and Michael addition

“…In this work, we report the construction of a novel series of hyperbranched polymeric FPA-PA adhesives by a one-step method using branched polyamines PA 4N , PA 5N , and PA 6N as reaction substrates and p-formylphenyl acrylate (FPA) [46][47][48][49][50] with both carbon-carbon double bonds and aldehyde groups (Scheme 1). Branched polyamines obtained from the reaction of methyl acrylate with ethylenediamine, diethylenetriamine and triethylenetetramine have the advantage of being easy to prepare and having a large number of amino groups.…”
