Abstract
Polyester monofilaments were grafted with methacrylic acid monomer in order to improve the water absorption and dye uptake characteristics. Kinetic parameters like percent grafting and grafting efficiency were measured as a function of concentration of monomer, initiator concentr ation, time of reaction, and temperature. The results show that the ra te of grafting is proportional to the 0.167 power of the monomer conce ntration and the 0.545 power of the initiator concentration. The activ ation energy for grafting, calculated from an Arrhenius plot, was foun d to be 11.12 kcal . mol(-1). Water absorption and dye uptake were tre mendously improved by grafting.
