The synthesis and polymerization of new unsaturated monomers derived from acrylic acid and an aliphatic-aromatic glycol is reported. Values of k(p)/k(t)(1/2) were obtained for the monoacrylate monomer and compared with those found for other acrylic monomers. The thermal properties of the starting glycol (Bis[2-hydroxyethyl]terephthalate), monomers (monoacrylate and diacrylate) and linear polymer were determined by calorimetric techniques. The results show the influence of intermolecular interactions (hydrogen bondings) on these properties.
