Description

The present work has as objectives the obtention and characterization of graft copolymer by irradiation. The polymer used was Nylon 6.6, the monomer was N, N-dimethylacrylamide and the solvent was the formic acid. The solutions were irradiated in 60 Co source in interval dose of 0-20 kGy at two different dose rates (o,20 and 1,02 kGy/h). The results showed that the values of grafting percentage increase or decrease depending of the type of reaction: crosslinking or chain scission. The Tm values decreased with the increasing of the dose in both dose rate. (author)
