Some physical properties of the graft copolymers of wool with acrylate monomers namely, methylacrylate, ethylacrylate, n‐butylacrylate and methylmethacrylate are investigated. The results show that the moisture regain decreases considerably after grafting; the density also decreases after an initial increase at low percentage of polymer deposition. With the grafting of low T g polymers the breaking elongation increases, initial modulus decreases and elastic recovery increases; a reverse trend is found with the grafting of high T g polymers. The dynamic mechanical properties of all grafted samples are also reported.
