Abstract :In this study graft-copolymerization reactions of acrylamide with polyinsert ignore into journalissuearticles values(ethylene te- rephthalate); insert ignore into journalissuearticles values(PET); fibers were studied by Chemical initiation technique using benzoyl peroxide as initiator. We have observed that the extent of grafting depended upon the time, the initiator, and monomer concentration, as well as temperature. The magnitude of the grafting enhanced by increasing benzoyl peroxide concentration up to 4xl0~3mole/1 and shovved a plateau between 4xl0~3 mole/1 and 10xl0~3 mole/1 then decreased by futher increase in benzoyl peroxide concentration. There was also an optimal temperature insert ignore into journalissuearticles values(75°C); for grafting; below or above this temperature, lower grafting was obtaihed. On the other hand, the grafting increased upon increase of acrylamide concentration within the range studied. The moisture regain and dyeability properties of the grafted PET were also exa- mined.
