The synthesis and characterization of photopolymerizable unsaturated α , ω ‐bismaleate poly(ethylene terephthalate) oligomer resins based on glycolysis of PET waste using diethylene glycol and the study of their photopolymerization with divinyl ethers have been described in a previous article. The use of PET glycolysis by DEG can be problematic because this oligoester is partially crystalline. The objective of this paper is to develop the UV‐curing technology for a new kind of glycolysate that are completely amorphous. Glycolysates with different molecular weights have been synthesized and functionalized by a methyl hemiester of maleic acid. The photopolymerization of these new functionalized oligoesters with divinyl ether is studied and the materials obtained are characterized. The influence of the glycolysate structures on the properties of the crosslinked materials is highlighted.
