BS>The preparation of stable, cross-linked polypropylene by irradiation is described. In an example, sections of polypropylene were irradiated to 40 x 10/sup 6/ rep in N/sub 2/ over the range 60 to 200 deg C and percent cross- linking was determined by dissolution in toluene. It was found that maximum cross-linking occurs at 100 to 125 deg C. In other examples it is shown that annealing between 130 and 200 deg C results in a flexible product. The polypropylene can be blended with polyethylene prior to irradiation to produce another series of useful products. (T.R.H.)
