Abstract
The effect of isotacticity of polypropylene(PP) on its radiation stabi lity has been investigated in the present work. It was found that (1) The G value of Ha and CH4 is smaller if isotacticity of PP is higher; (2) It is easier to be crosslinked by radiation for the PP with higher isotacticity; (3) The shape of DSC peak changes smaller after irradia tion for PP with higher isotacticity. These results have been explaine d by the measurement of C-13-NMR and small angle X-ray scattering.
