| Résumé : |
Different acrylic polymer retanning agents were synthesized with acrylic acid as the primary monomer and eight other acrylate monomers (MAA-methyl acrylic acid, EA-ethyl acrylate, BA-butyl acrylate, VAc-vinyl acetate, MA-methyl acrylate, AM-acrylamide, IA-Itaconic acid, HEA-2-hydroxyethyl acrylate) as commoners. The eight copolymers were applied in the retanning process separateley and the elasticity of the resultant leather was discussed. The results showed that the leather elasticity could be tested by calculating young's modulus of the elastic deformation, which ws a variable region on the load-displacement curve, and young's modulus of the elastic deformation could serve as an independent parameter in characterizing leather's physical properties. The relation between the elasticity and the dosage of copolymer was discussed, and it revealed that every comonomer had a proper dosage at which level the resultant leather showed the lowest young's modulus. Then the effects of the eight comonomers on leather elasticity were compared under the same condition. It showed that the soft comonomers, BA and EA, contributed more in leather elasticity than other selected comonomers. |
